What does it mean when email is badly formatted?

Sometimes however message text can be poorly formatted and difficult to read. This is known as “garbled text” and can be caused by the encoding used by the sender’s email system. One workaround is to use the Message text garbled option within Gmail.

Can you change email in Firebase Auth?

You will also need to reauthenticate the login prior to calling this as Firebase requires a fresh authentication to perform certain account functions such as deleting the account, changing the email or the password.

How do I use Firebase authentication email?

How do I know if my email is using Firebase?

If you want to check whether an email address is already in use before registering the user, the Firebase Admin SDK has a method to look up a user by their email address: admin. auth(). getUserByEmail(email) .

Why is my email gibberish?

When you get a message, Gmail tries to guess what encoding the sender used so that it can properly open and display the message. If Gmail guesses wrong, you usually end up with a screen full of gibberish because the message wasn’t translated properly from one encoding to the other.

How do I fix my format in Gmail?

How do I change my Firebase email template?

Open your project in the Firebase console. Go to the Email Templates page in the Auth section. In any of the Email Types entries, click the pencil icon to edit the email template. Click customize action URL, and specify the URL to your custom email action handler.

How do you update your email address?

Does Firebase UID change?

It’s best to use the Firebase Authentication UID as a Cloud Firestore document ID in this case. You might be tempted to use an email address as a per-user document ID, but I don’t recommend that at all, as email addresses can change over time. UIDs will never change.

Can Firebase send emails?

Made by Firebase

Composes and sends an email based on the contents of a document written to a specified Cloud Firestore collection.

How do you implement email registration and login using Firebase in react?

Should I use Firebase authentication?

Firebase is a good choice if you plan to either write a brand-new application or rewrite an existing one from scratch. Additionally, firebase helps in the easy storing and retrieval of dynamic content. If you decide to develop the application without any form of custom coding the backend, firebase makes this easy.

What is action code settings?

public class ActionCodeSettings extends Object. implements Parcelable. Structure that contains the required continue/state URL with optional Android and iOS bundle identifiers. The stateUrl used to initialize this class is the link/deep link/fallback url used while constructing the Firebase dynamic link.

What is glif Web?

The Glif Wallet is a Filecoin web wallet built with Next. js that allows you to: send and receive Filecoin with your Ledger device.

How do you format an email?

What is the correct format of email address?

A valid email address consists of an email prefix and an email domain, both in acceptable formats. The prefix appears to the left of the @ symbol. The domain appears to the right of the @ symbol. For example, in the address [email protected], “example” is the email prefix, and “mail.com” is the email domain.

Why are some of my emails unreadable?

The sender used an e-mail program that did not mark messages with a language encoding (character set), or marked messages with an incorrect encoding setting. In this case, we will see unreadable characters when we open the received message in our Outlook.

How do I fix formatting in Outlook?

[Solved] The email address is badly formatted – Flutter firebase

Asked by Upgrade T on May 02, 2022 (source).

when I uses flutter firebase email password auth it shows email adress badly formated. name and vehicle number is also pass to the database when authentication process is there any problem in it. why it occurs. if someone can help me to find out the problem help me

Question answered by Frank v (source).

You’re calling:

signUp( emailController.text, passwordController.text, role, vehicleNo.text, name.text);

And signUp is defined as:

void signUp(String name, String email, String password, String role, String vehicleNo) async {

So the order of the arguments is different between the two, leading you to call Firebase with the password value as the email address and the role value as the password.

Article List

Be sure that the format is @.. For example: [email protected].

An email address must consist of two parts, local and domain, separated by the @ symbol; the combined length may be no more than 256 characters.

If the issue persists, then copy / paste the email address from the system into notepad (or a similar text program) and review the email address to ensure there are no special characters included in it. If you see a special character included in the email address remove it and then copy / paste back into the ScholarOne system.

How to change email in firebase auth?

You can do this directly with AngularFire2, you just need to add “currentUser” to your path.

this.af.auth.currentUser.updateEmail(email) .then(() => { … });

You will also need to reauthenticate the login prior to calling this as Firebase requires a fresh authentication to perform certain account functions such as deleting the account, changing the email or the password.

For the project I just implemented this on, I just included the login as part of the change password/email forms and then called “signInWithEmailAndPassword” just prior to the “updateEmail” call.

To update the password just do the following:

Authenticate with Firebase Using Email Link in Android

You can use Firebase Authentication to sign in a user by sending them an email containing a link, which they can click to sign in. In the process, the user’s email address is also verified.

There are numerous benefits to signing in by email:

Low friction sign-up and sign-in.

Lower risk of password reuse across applications, which can undermine security of even well-selected passwords.

The ability to authenticate a user while also verifying that the user is the legitimate owner of an email address.

A user only needs an accessible email account to sign in. No ownership of a phone number or social media account is required.

A user can sign in securely without the need to provide (or remember) a password, which can be cumbersome on a mobile device.

An existing user who previously signed in with an email identifier (password or federated) can be upgraded to sign in with just the email. For example, a user who has forgotten their password can still sign in without needing to reset their password.

Before you begin

Set up your Android project

If you haven’t already, add Firebase to your Android project. Using the Firebase Android BoM, declare the dependency for the Firebase Authentication Android library in your module (app-level) Gradle file (usually app/build.gradle ). Also, as part of setting up Firebase Authentication, you need to add the Google Play services SDK to your app. Java dependencies { // Import the BoM for the Firebase platform implementation platform(‘com.google.firebase:firebase-bom:30.3.1’) // Declare the dependency for the Firebase Authentication library // When using the BoM, you don’t specify versions in Firebase library dependencies implementation ‘com.google.firebase:firebase-auth’

// Also declare the dependency for the Google Play services library and specify its version implementation ‘com.google.android.gms:play-services-auth:20.2.0’ } By using the Firebase Android BoM, your app will always use compatible versions of the Firebase Android libraries. (Alternative) Declare Firebase library dependencies without using the BoM If you choose not to use the Firebase BoM, you must specify each Firebase library version in its dependency line. Note that if you use multiple Firebase libraries in your app, we highly recommend using the BoM to manage library versions, which ensures that all versions are compatible. dependencies { // Declare the dependency for the Firebase Authentication library // When NOT using the BoM, you must specify versions in Firebase library dependencies implementation ‘com.google.firebase:firebase-auth:21.0.6’

// Also declare the dependency for the Google Play services library and specify its version implementation ‘com.google.android.gms:play-services-auth:20.2.0’ } Kotlin+KTX dependencies { // Import the BoM for the Firebase platform implementation platform(‘com.google.firebase:firebase-bom:30.3.1’) // Declare the dependency for the Firebase Authentication library // When using the BoM, you don’t specify versions in Firebase library dependencies implementation ‘com.google.firebase:firebase-auth-ktx’

// Also declare the dependency for the Google Play services library and specify its version implementation ‘com.google.android.gms:play-services-auth:20.2.0’ } By using the Firebase Android BoM, your app will always use compatible versions of the Firebase Android libraries.

// Also declare the dependency for the Google Play services library and specify its version implementation ‘com.google.android.gms:play-services-auth:20.2.0’ }

Enable Email Link sign-in for your Firebase project

To sign in users by email link, you must first enable the Email provider and Email link sign-in method for your Firebase project:

In the Firebase console, open the Auth section. On the Sign in method tab, enable the Email/Password provider. Note that email/password sign-in must be enabled to use email link sign-in. In the same section, enable Email link (passwordless sign-in) sign-in method. Click Save.

Send an authentication link to the user’s email address

To initiate the authentication flow, present the user with an interface that prompts the user to provide their email address and then call sendSignInLinkToEmail to request that Firebase send the authentication link to the user’s email.

Construct the ActionCodeSettings object, which provides Firebase with instructions on how to construct the email link. Set the following fields: url : The deep link to embed and any additional state to be passed along. The link’s domain has to be whitelisted in the Firebase Console list of authorized domains, which can be found by going to the Sign-in method tab (Authentication -> Sign-in method). The link will redirect the user to this URL if the app is not installed on their device and the app was not able to be installed.

Otherwise the first domain is automatically selected. Java ActionCodeSettings actionCodeSettings = ActionCodeSettings.newBuilder() // URL you want to redirect back to. The domain (www.example.com) for this // URL must be whitelisted in the Firebase Console. .setUrl(“https://www.example.com/finishSignUp?cartId=1234”) // This must be true .setHandleCodeInApp(true) .setIOSBundleId(“com.example.ios”) .setAndroidPackageName( “com.example.android”, true, /* installIfNotAvailable */ “12” /* minimumVersion */) .build(); MainActivity.java Kotlin+KTX val actionCodeSettings = actionCodeSettings { // URL you want to redirect back to.

Ask the user for their email. Send the authentication link to the user’s email, and save the user’s email in case the user completes the email sign-in on the same device. Java FirebaseAuth auth = FirebaseAuth.getInstance(); auth.sendSignInLinkToEmail(email, actionCodeSettings) .addOnCompleteListener(new OnCompleteListener() { @Override public void onComplete(@NonNull Task task) { if (task.isSuccessful()) { Log.d(TAG, “Email sent.”); } } }); MainActivity.java Kotlin+KTX Firebase.auth.sendSignInLinkToEmail(email, actionCodeSettings) .addOnCompleteListener { task -> if (task.isSuccessful) { Log.d(TAG, “Email sent.”) } } MainActivity.kt

Complete sign in with the email link

Security concerns

To prevent a sign-in link from being used to sign in as an unintended user or on an unintended device, Firebase Auth requires the user’s email address to be provided when completing the sign-in flow. For sign-in to succeed, this email address must match the address to which the sign-in link was originally sent.

You can streamline this flow for users who open the sign-in link on the same device they request the link, by storing their email address locally – for instance using SharedPreferences – when you send the sign-in email. Then, use this address to complete the flow. Do not pass the user’s email in the redirect URL parameters and re-use it as this may enable session injections.

After sign-in completion, any previous unverified mechanism of sign-in will be removed from the user and any existing sessions will be invalidated. For example, if someone previously created an unverified account with the same email and password, the user’s password will be removed to prevent the impersonator who claimed ownership and created that unverified account from signing in again with the unverified email and password.

Also make sure you use an HTTPS URL in production to avoid your link being potentially intercepted by intermediary servers.

Completing sign-in in an Android App

Firebase Authentication uses Firebase Dynamic Links to send the email link to a mobile device. For sign-in completion via mobile application, the application has to be configured to detect the incoming application link, parse the underlying deep link and then complete the sign-in.

Firebase Auth uses Firebase Dynamic Links when sending a link that is meant to be opened in a mobile application. In order to use this feature, Dynamic Links must be configured in the Firebase Console.

Enable Firebase Dynamic Links: In the Firebase console, open the Dynamic Links section. If you have not yet accepted the Dynamic Links terms and created a Dynamic Links domain, do so now. If you already created a Dynamic Links domain, take note of it. A Dynamic Links domain typically looks like the following example: example.page.link You will need this value when you configure your Apple or Android app to intercept the incoming link. Configuring Android applications: In order to handle these links from your Android application, the Android package name needs to be specified in the Firebase Console project settings. In addition, the SHA-1 and SHA-256 of the application certificate need to be provided. Now that you have added a dynamic link domain and ensured that your Android app is configured correctly, the dynamic link will redirect to your application, starting from the launcher activity. If you want the dynamic link to redirect to a specific activity, you will need to configure an intent filter in your AndroidManifest.xml file. This can be done by either specifying your dynamic link domain or the email action handler in the intent filter. By default, the email action handler is hosted on a domain like the following example: PROJECT_ID .firebaseapp.com/ Caveats: Do not specify the URL you set on the actionCodeSettings in your intent filter. When creating your dynamic link domain you may have also created a short URL link. This short URL will not be passed; do not configure your intent filter to catch it with an android:pathPrefix attribute. This means that you will not be able to catch different dynamic links in different parts of your application. However, you can check the mode query parameter in the link to see what operation is attempting to be performed, or use SDK methods such as isSignInWithEmailLink to see if a link that your app has received does what you want. For more on receiving dynamic links, refer to Receiving Android Dynamic Links instructions.

Verify link and sign in

After you receive the link as described above, verify that it is meant for email link authentication and complete the sign in.

Java FirebaseAuth auth = FirebaseAuth.getInstance(); Intent intent = getIntent(); String emailLink = intent.getData().toString(); // Confirm the link is a sign-in with email link. if (auth.isSignInWithEmailLink(emailLink)) { // Retrieve this from wherever you stored it String email = “[email protected]”; // The client SDK will parse the code from the link for you. auth.signInWithEmailLink(email, emailLink) .addOnCompleteListener(new OnCompleteListener() { @Override public void onComplete(@NonNull Task task) { if (task.isSuccessful()) { Log.d(TAG, “Successfully signed in with email link!”); AuthResult result = task.getResult(); // You can access the new user via result.getUser() // Additional user info profile *not* available via: // result.getAdditionalUserInfo().getProfile() == null // You can check if the user is new or existing: // result.getAdditionalUserInfo().isNewUser() } else { Log.e(TAG, “Error signing in with email link”, task.getException()); } } }); } MainActivity.java Kotlin+KTX val auth = Firebase.auth val intent = intent val emailLink = intent.data.toString() // Confirm the link is a sign-in with email link. if (auth.isSignInWithEmailLink(emailLink)) { // Retrieve this from wherever you stored it val email = “[email protected]” // The client SDK will parse the code from the link for you. auth.signInWithEmailLink(email, emailLink) .addOnCompleteListener { task -> if (task.isSuccessful) { Log.d(TAG, “Successfully signed in with email link!”) val result = task.result // You can access the new user via result.getUser() // Additional user info profile *not* available via: // result.getAdditionalUserInfo().getProfile() == null // You can check if the user is new or existing: // result.getAdditionalUserInfo().isNewUser() } else { Log.e(TAG, “Error signing in with email link”, task.exception) } } } MainActivity.kt

To learn more on how to handle sign-in with email link in an Apple application, refer to the Apple platforms guide.

To learn about how to handle sign-in with email link in a web application, refer to the Web guide.

Linking/re-authentication with email link

You can also link this method of authentication to an existing user. For example a user previously authenticated with another provider, such as a phone number, can add this method of sign-in to their existing account.

The difference would be in the second half of the operation:

Java // Construct the email link credential from the current URL. AuthCredential credential = EmailAuthProvider.getCredentialWithLink(email, emailLink); // Link the credential to the current user. auth.getCurrentUser().linkWithCredential(credential) .addOnCompleteListener(new OnCompleteListener() { @Override public void onComplete(@NonNull Task task) { if (task.isSuccessful()) { Log.d(TAG, “Successfully linked emailLink credential!”); AuthResult result = task.getResult(); // You can access the new user via result.getUser() // Additional user info profile *not* available via: // result.getAdditionalUserInfo().getProfile() == null // You can check if the user is new or existing: // result.getAdditionalUserInfo().isNewUser() } else { Log.e(TAG, “Error linking emailLink credential”, task.getException()); } } }); MainActivity.java Kotlin+KTX // Construct the email link credential from the current URL. val credential = EmailAuthProvider.getCredentialWithLink(email, emailLink) // Link the credential to the current user. Firebase.auth.currentUser!!.linkWithCredential(credential) .addOnCompleteListener { task -> if (task.isSuccessful) { Log.d(TAG, “Successfully linked emailLink credential!”) val result = task.result // You can access the new user via result.getUser() // Additional user info profile *not* available via: // result.getAdditionalUserInfo().getProfile() == null // You can check if the user is new or existing: // result.getAdditionalUserInfo().isNewUser() } else { Log.e(TAG, “Error linking emailLink credential”, task.exception) } } MainActivity.kt

This can also be used to re-authenticate an email link user before running a sensitive operation.

Java // Construct the email link credential from the current URL. AuthCredential credential = EmailAuthProvider.getCredentialWithLink(email, emailLink); // Re-authenticate the user with this credential. auth.getCurrentUser().reauthenticateAndRetrieveData(credential) .addOnCompleteListener(new OnCompleteListener() { @Override public void onComplete(@NonNull Task task) { if (task.isSuccessful()) { // User is now successfully reauthenticated } else { Log.e(TAG, “Error reauthenticating”, task.getException()); } } }); MainActivity.java Kotlin+KTX // Construct the email link credential from the current URL. val credential = EmailAuthProvider.getCredentialWithLink(email, emailLink) // Re-authenticate the user with this credential. Firebase.auth.currentUser!!.reauthenticateAndRetrieveData(credential) .addOnCompleteListener { task -> if (task.isSuccessful) { // User is now successfully reauthenticated } else { Log.e(TAG, “Error reauthenticating”, task.exception) } } MainActivity.kt

However, as the flow could end up on a different device where the original user was not logged in, this flow might not be completed. In that case, an error can be shown to the user to force them to open the link on the same device. Some state can be passed in the link to provide information on the type of operation and the user uid.

Differentiating email/password from email link

In case you support both password and link-based sign in with email, to differentiate the method of sign in for a password/link user, use fetchSignInMethodsForEmail . This is useful for identifier-first flows where the user is first asked to provide their email and then presented with the method of sign-in:

Java auth.fetchSignInMethodsForEmail(email) .addOnCompleteListener(new OnCompleteListener() { @Override public void onComplete(@NonNull Task task) { if (task.isSuccessful()) { SignInMethodQueryResult result = task.getResult(); List signInMethods = result.getSignInMethods(); if (signInMethods.contains(EmailAuthProvider.EMAIL_PASSWORD_SIGN_IN_METHOD)) { // User can sign in with email/password } else if (signInMethods.contains(EmailAuthProvider.EMAIL_LINK_SIGN_IN_METHOD)) { // User can sign in with email/link } } else { Log.e(TAG, “Error getting sign in methods for user”, task.getException()); } } }); MainActivity.java Kotlin+KTX Firebase.auth.fetchSignInMethodsForEmail(email) .addOnSuccessListener { result -> val signInMethods = result.signInMethods!! if (signInMethods.contains(EmailAuthProvider.EMAIL_PASSWORD_SIGN_IN_METHOD)) { // User can sign in with email/password } else if (signInMethods.contains(EmailAuthProvider.EMAIL_LINK_SIGN_IN_METHOD)) { // User can sign in with email/link } } .addOnFailureListener { exception -> Log.e(TAG, “Error getting sign in methods for user”, exception) } MainActivity.kt

As described above email/password and email/link are considered the same EmailAuthProvider (same PROVIDER_ID ) with different methods of sign-in.

Next steps

After a user signs in for the first time, a new user account is created and linked to the credentials—that is, the user name and password, phone number, or auth provider information—the user signed in with. This new account is stored as part of your Firebase project, and can be used to identify a user across every app in your project, regardless of how the user signs in.

In your apps, you can get the user’s basic profile information from the FirebaseUser object. See Manage Users.

In your Firebase Realtime Database and Cloud Storage Security Rules, you can get the signed-in user’s unique user ID from the auth variable, and use it to control what data a user can access.

You can allow users to sign in to your app using multiple authentication providers by linking auth provider credentials to an existing user account.

How to check if an email address is already in use in Firebase on iOS?

Any user account in Firebase Authentication that has an email address can be verified, it doesn’t have to be an email+password account. To verify the email address for a user call user.sendEmailVerification() .

If you want to check whether an email address is already in use before registering the user, the Firebase Admin SDK has a method to look up a user by their email address: admin.auth().getUserByEmail(email) . This method requires administrative privileges and (like all of the Admin SDK) should only be run in a trusted environment – typically a server you control or Cloud Functions for Firebase.

Firebase: e-mail address is badly formatted

Hi,

I have amended my build gradle from an earlier post, when I try to connect to my firebase I now receive the error E-mail address is badly formatted. I previously imported the test firebase plugin to my app and this worked fine, I have just amended the details to connect to my own,

What would be causing this issue within my app? and what areas of my code would you want me to post to check through?

Thanks

Edd

The email address is badly formatted Firebase

Your code to set email is incorrect. You are setting email to the value of the EditText for password .

In method CheckLogin() , change:

String email = mloginPassField.getText().toString().trim();

to:

String email = mLoginEmailField .getText().toString().trim();

Simply use Edittext named as Email and Password you need not do anything. the error comes up only if you use plaintext for both…
