Configure Azure AD Single Sign-On (SSO) for WordPress using OAuth | Azure AD SSO

WordPress Azure AD SSO uses OAuth Authorization flow to provide users secure access to WordPress sites. With our WordPress OAuth Single Sign-On (SSO) plugin, Azure AD acts as the OpenID Connect and OAuth provider, ensuring secure login for WordPress websites.

The integration of WordPress Azure AD simplifies and secures the login process using Azure AD SSO. This solution allows employees to access their WordPress sites with a single click using their Azure Active Directory (Azure AD) credentials, completely removing the need to store, remember, and reset multiple passwords.

In addition to offering Azure AD Single Sign-On (SSO) functionality, the plugin also provides advanced SSO features like user profile attribute mapping, role mapping, and Azure multi-tenant login and providing site access based on organization email domains. For a detailed overview of the features, check out the WordPress OAuth Single Sign-On (SSO) plugin. You can follow the below steps to setup Azure Active Directory (Azure AD) SSO with WordPress.
