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](https://auth0.com/docs/manage-users/user-accounts/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 ---
