Configure Azure B2C Single Sign-On (SSO) with WordPress OAuth

Overview

Azure B2C Single Sign-On (SSO) for WordPress uses OAuth Authorization flow to provide users secure access to WordPress site. With our WordPress OAuth Single Sign-On (SSO) plugin, Azure B2C acts as the OpenID Connect and OAuth provider, ensuring secure Single Sign-On (SSO) login for WordPress websites. The integration of WordPress with Azure B2C simplifies and secures the login process using Azure B2C OAuth. This solution allows employees to access their WordPress sites with a single click using their Azure B2C credentials, completely removing the need to store, remember, and reset multiple passwords. In addition to offering Azure B2C SSO functionality, the plugin extends its support to various IDPs, including Azure AD, Office 365, and specialized providers, offering robust Single Sign-On (SSO) capabilities like multi-tenant login, role mapping, and user profile attribute mapping. 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 B2C Single Sign-On (SSO) with WordPress.
