Prevent user from using temporary or fake email addresses

There’re many websites that provide one-time or fake email address to register an account, is there an option for auth0 to block these “fake” users?

I mean, I accept free emails like gmail or outlook, but not those onetime fakes.

The reason is simple, gmail and outlook has risk controls, they sometimes verify the phone number or user identity, it will give me some sort of protection.

I don’t want to give free trial to untrusted onetime users.

Hi @amooW6ojoh

Welcome back to the Auth0 Community!

Thank you for posting your question. Unfortunately, Auth0 doesn’t offer an out-of-the-box solution to handle this kind of signups. You can mount a third-party provider in the Pre-user registration trigger of an Action that would check the email address or create an action that would deny the registration by checking the domain if you see the pattern in the registrations. However, I think it’s an excellent idea for the feature, so I would encourage you to open up a new thread in the Feedback category and share more insight regarding your use case!

Thanks
