Configure Google Single Sign-On (SSO) with WordPress OAuth – WordPress Google SSO

Set up Single Sign-On (SSO) on your WordPress website via Google Apps with the WordPress OAuth & OpenID Connect Single Sign-On plugin via WordPress SSO. Implementing G Suite SSO allows users to log into your websites and applications with a single set of credentials using the G Suite login credentials.

Google Single Sign-On or GSuite, acts as the OAuth Provider and WordPress acts as the OAuth Client. WordPress Google SSO provides smooth login between these two, removing the need to remember usernames and passwords. If you are looking for Google Classroom SSO, you can visit the setup guide here.

The Google Single Sign-On via OAuth WordPress plugin also provides advanced SSO features like user profile attribute mapping, role mapping, and role-based access for user profiles. You can also protect your complete WordPress site behind Google SSO. Google login via WordPress OAuth SSO secures the user’s login process and improves user authentication authority.

Using the OAuth SSO plugin, you can allow or restrict your organization users as well as guest users based on their email domains such as organization/comapny domain or personal domain such as gmail.com Follow the steps in the guide below to set up your WordPress SSO via installing this plugin.
