Lockout or disable a user from form

[enchev]

The only option I can suggest is described in this thread:

Extend user to allow disable it

I would like to extend the user entity to allow disable it and prevent it from logging in. Extend the user to create the field is no problem, but prevent it from logging in doesn't seem possible without changing the file AuthController.cs and adding it to ignore list. Am I right?

In Blazor this is AccountController.
