@yeestrada can you share the relevant code on the forum? That makes it more useful for other people to read it another time.

I see that the guide you follow use an old Laravel version. Do you use that version (5.6) or the latest?

There are multiple options that result in the 401, it can that you have an auth requirement on the api group (in the RouteServiceProvider) or something else that I didn't directly see.

One thing that I see is that your UserTest does nothing with the database but your AuthController does (the unique validation rule will execute a query to your database) I'm not sure how that error in your validation will return.
