revokeTokenWithAuthorizationCode(String authorizationCode) → Future<void>
Apple only. Users signed in with Apple provider can revoke their token using an authorization code. Authorization code can be retrieved on the user credential i.e. userCredential.additionalUserInfo.authorizationCode

Sends a password reset email to the given email address.
sendSignInLinkToEmail({required String email, required ActionCodeSettings actionCodeSettings}) → Future<void>
Sends a sign in with email link to provided email address.
setLanguageCode(String? languageCode) → Future<void>
When set to null, sets the user-facing language code to be the default app language.
setPersistence(Persistence persistence) → Future<void>
Changes the current type of persistence on the current Auth instance for the currently saved Auth session and applies this type of persistence for future sign-in requests, including sign-in with redirect requests.
setSettings({bool appVerificationDisabledForTesting = false, String? userAccessGroup, String? phoneNumber, String? smsCode, bool? forceRecaptchaFlow}) → Future<void>
Updates the current instance with the provided settings.
signInAnonymously() → Future<UserCredential>
Asynchronously creates and becomes an anonymous user.
signInWithAuthProvider(AuthProvider provider) → Future<UserCredential>
