The SysUserAuthentication model pattern is for integration user registration and login into your Turnkey App.

This pattern uses the ASP.NET Core Identity architecture to add user registration and sign-in. It handles both authentication (who you are) and authorization (what you are permitted to do).

The Pattern supports external login using Google, Open ID, Microsoft, Facebook. [[Documentation:External login services in MDriven Turnkey|Check here]] for details on how to login with third party providers.
