Auth0 Lock Email Validation on signup

On Universal Signup form is there any way to validate email address? Where I can Block Or prevent free email eddresses E.G. Yahoo.Com, Gmail.Com, and Hotmail.Com.

Hey there!

I’m not 100% sure what you mean by free email addresses but you can achieve that using rules.

Got to your Dashboard -> Rules > Whitelist for a Specific App rule for example.

You’ll get the idea how it works.
