Hey @pnieto! Thanks for following the tutorial! I seem to have missed your comment earlier, so hopefully you got it resolved since then! If not, one simple way to handle options like that is using Auth0 rules.
Rules run right after an authentication request, so you can do just about anything here, such as disabling new signups, only allowing signups from certain domains, disabling social login, etc. You can also modify user information. It’s really powerful and simple to use.
There’s even a sample Rule pre-written that shows how to disable social signups. If you want to see how that one works, go to your dashboard, click on “Rules” on the lefthand side, and then click on “Create rule”. Then find the one that says “Disable social signups”. Hope that helps!
