Auth - Provider - Email

The Email/Password provider allows you to sign in a user with an email address and password.

This is the simplest form of user authentication provided by the Firebase platform.

Enable the Provider#

Log in to you Firebase console and go to the Authentication section of your application. Click on Sign-In Method and select the Email/Password provider and make sure it is enabled as in the screenshot below.

Sign up new users#

Creating a user account requires you to create functionality to gather their email and password and then call the createUserWithEmailAndPassword function.

This function tries to create a new user account with the given email address and password. If successful, it also signs the user in into the app.

Access the signed-in user with getCurrentUser().

Upon successful completion, this operation triggers an FirebaseAuthEvent.AUTHSTATE_CHANGED event and it will trigger a FirebaseAuthEvent.CREATE_USER_WITH_EMAIL_COMPLETE on success or failure.

FirebaseAuth.service.addEventListener(
FirebaseAuthEvent.CREATE_USER_WITH_EMAIL_COMPLETE,
createUserWithEmailAndPassword_completeHandler );
FirebaseAuth.service.createUserWithEmailAndPassword( email, password );

The following handler can be used to determine the success or failure of the call.

private function createUserWithEmailAndPassword_completeHandler( event:FirebaseAuthEvent ):void
{
trace( "createUserWithEmailAndPassword(): complete: " + event.success +"::"+event.message );
FirebaseAuth.service.removeEventListener(
FirebaseAuthEvent.CREATE_USER_WITH_EMAIL_COMPLETE,
createUserWithEmailAndPassword_completeHandler );
}

Of course you can use your global FirebaseAuthEvent.AUTHSTATE_CHANGED to listen for sign in success as well as this handler.

Sign in existing users#

Similarly to the creation process you will need to gather the user's email and password and then call the signInWithEmailAndPassword function.

This function tries to sign in a user with the given email address and password, and does not attempt to create the user if it does not exist.

Access the signed-in user with getCurrentUser().

Upon successful completion, this operation triggers an FirebaseAuthEvent.AUTHSTATE_CHANGED event and it will trigger a FirebaseAuthEvent.SIGNIN_WITH_EMAIL_COMPLETE on success or failure.

FirebaseAuth.service.addEventListener(
FirebaseAuthEvent.SIGNIN_WITH_EMAIL_COMPLETE,
signInWithEmailAndPassword_completeHandler );
FirebaseAuth.service.signInWithEmailAndPassword( email, password );

The following handler can be used to determine the success or failure of the call.

private function signInWithEmailAndPassword_completeHandler( event:FirebaseAuthEvent ):void
{
trace( "signInWithEmailAndPassword(): complete: " + event.success +"::"+event.message );
FirebaseAuth.service.removeEventListener(
FirebaseAuthEvent.SIGNIN_WITH_EMAIL_COMPLETE,
signInWithEmailAndPassword_completeHandler );
if (event.success)
{
var user:FirebaseUser = FirebaseAuth.service.getCurrentUser();
trace( user.displayName );
}
}

Of course you can use your global FirebaseAuthEvent.AUTHSTATE_CHANGED to listen for sign in success as well as this handler.
