If you’ve just set up your new auth0 tenant and created (or used the auth0 angular demo repo), you’ve probably encountered this error when your Angular app tries to authenticate with auth0: Unauthorized with status 401. Even if you followed the instructions on how to populate the config and filled in the right details, it still shows. This is a bug that is reported here last 2020 and surprisingly still exists now.
The solution is quite simple:
- Change your application’s type from SPA to Regular Web Application.
- Set the Token Endpoint Authentication Method from Post to None.
- Bring back your application’s type to SPA.
Fortunately, people report issues, and solutions were documented.
