Can Domain Whitelisting be implemented using next auth

[hussamkhatib]

Hi,
I wanted to know if it is possible to enable domain whitelisting in next auth. I don't have next auth set up in my project yet as I'm exploring if this can be implemented or not.

Eg [email protected] , [email protected] , [email protected]
When the user tries to sign up it should only person1 to sign up and not the other 2 persons.
Note: I don't want the false entries to be signed up and denied access in the app instead don't create an entry in the database at all and handle the error gracefully if possible.
