Auth0 treats sign-up with Google as login so we can create two accounts with the same email on our system with the Google sign-in and password form. How we can prevent that?
Hi @info66
Welcome to the Auth0 Community!
Thank you for posting your question. The only way you can prevent this is to utilize the account-linking feature User Account Linking. This will allow users to log in to the same account from both sources. Alternatively, you can go with a Pre-User registration Action that would prevent user signup from Database connection when the same email already exists in your database.
I hope this will help you.
Thanks
Dawid
