Do I need to implement register if password is disabled (only social login through oidc) ?

I don’t know why, but social login for me does not automatically create an account. I would also like to disable registrations, but then I do not see how an account would be made…

I'm guessing it's because it needs to store the user data as a user, and that's considered a registration but I'm just confused about what a registration page will do, it seems like for my user schema the input_mapper should fill everything out
