What if i used my custom DB to authenticate my users from auth0 having single email id which is assigned in multiple user id’s/accounts.

As of now in my current web application users can logged in, because in my custom DB UserId is primary key and we didn’t make email id as unique key. We used only UserId as a login parameter.

Hi @shivam2

Welcome to the Auth0 Community!

Thank you for posting your question. Can you confirm that I understand correctly that in your custom database, the email address is not unique, so when users are trying to log in via Auth0 Universal Login, they are using an email address and can’t log in because the script is finding multiple users associated with the email address.

Can you share more details about the login process to your application and the custom database script you are using to sign up and log in to your users?
