Validate data of new user registration

Hi everyone! Im new on this Keycloak world, and I have a question. Because I saw that I can register using Google, Facebook, etc…

What happened if I want to validate something before register a new user? For instance, I have a lot of clients, with a contract number…i want that only users with valid contract numbers are allowed to register on my keycloak DB…is that possible? Thanks in advance!


You hve to use the extension to validate the mobile number for this you can follow this github repository, it might help you.
