Firebase Authentication plugin allows users to login into your WordPress site
using their Firebase login credentials.
1. Features Included in the Firebase Premium Plugin
1.1: Allow login with Firebase and WordPress
In the Firebase Authentication Plugin, there are two different options to
enable login into your WordPress site.
Both Firebase and WordPress
When this option is enabled, the users that are present in your Firebase
project and the normal WordPress users both are allowed to login into
your WordPress site via the default wp-login form.
When this option is enabled, only the users that are present in your
Firebase project are allowed to login into your WordPress site via the
default wp-login form. The normal WordPress users are restricted to
login into the site. There is an option to allow only Administrators to
use the WordPress login.
1.2: Attribute mapping
When a user tries to login into the WordPress site using the Firebase
credentials, after successful authentication, if the user is not present in
the WordPress, a new user is created and while creating the user, you can
map any unique attribute received from the Firebase to your WordPress
username attribute. If you are using the firebase email password
authentication method, then you can also map the firebase email attribute to
the WordPress email profile attribute. Eg. you can map the Firebase
user-id received from Firebase to the WordPress username.
1.3: Auto register users in Firebase as well as WordPress
When a user tries to login into the WordPress site using Firebase
credentials and if the user is not present in the WordPress site, a new user
is auto-created in the Wordpress site with the email address received from
the Firebase with the Subscriber role. The user is created with a Random
password in WordPress, for security we do not sync the firebase passwords in
wordpress. The passwords are maintained in Firebase only such that Firebase
will be a single authentication source.
Other way around, if the user is not present in the Firebase and if the user
tries to register via the default WooCommerce registration form or the
default BuddyPress registration form, then the user is created in the
Firebase Authentication tab with the email address and the password that he
has entered on the WordPress site.
1.4: Login & Registration Form Integration (WooCommerce, BuddyPress)
Using the default Login form of WooCommerce and Buddypress, users can login
into the WordPress site by entering their firebase credentials. At the time
of registration, users will be auto-created in Firebase with the email and
password entered on the default registration form of WooCommerce and
1.5: Custom redirect URL after Login and Logout
This feature allows you to configure the URL wherever you want to redirect
users after login or after logout.
1.6: Firebase Email Verification
Email verification is a method of confirming that a subscriber has provided a valid email address and we have genuine registrations. It will also help in identifying if an email address is valid, inactive, or false. Your WordPress site is protected from spam registrations using the email verification feature of the Firebase authentication plugin.
Send verification email after registration
When you select the Send verification email after registration checkbox from the Advanced settings => Sync WordPress and Firebase users tab, then every user who will register on your site, that user will receive an email with a Verification link.
Do Not allow login if email is not verified
When you select the Do Not allow login if email is not verified checkbox from the Login settings => Advanced Sign in options tab, then only users with verified email addresses will be allowed to log in.
1.7: WP hooks to integrate your Custom/Third-party Login and Registration
If you are using any custom or third-party plugins for login and
registration form on your wordpress site, then we provide certain hooks to
integrate the firebase authentication with these login and registration
forms. We will provide you a code that you need to add in your functions.php
file. So that users can enter their firebase credentials on that login form
to login into the site. Users will be auto-created in the Firebase with the
email and password when they register into the wordpress site via your
custom registration form.
Note: Users will be auto created in the Firebase Authentication tab
with email and password and not in the Firestore
