Users appreciate this WordPress plugin for its effectiveness in integrating with various identity providers like Azure AD, Microsoft 365, and GSuite. The setup process is generally found to be straightforward and user-friendly, unlike other SSO plugins that can be complicated or require payment for basic functionalities. However, there are some drawbacks including missing library files, lack of instructions for configuration with specific services like Okta, and the inability to define the default role or disable logging out from the ID provider easily. Despite these issues, users find that the plugin excels in simplicity and functionality where others fall short.
