Our business’ use case is such that we can’t rely on/assume that each of our users has an email address.
Given that, we’d like to utilize username and password authentication as our primary connection/login option. Is it possible to do this with auth0, or it’s strictly required that every user in the auth0 user store needs to have an email associated with them, and they are always able to login with that email address (instead of only a username)?
Today we have an existing user store, where only a portion of our users have email addresses stored with their user record and they login using a username and password.
How would you recommend migrating to auth0 such that those users can continue to sign in to our product using their same username and password, and we don’t have to require that they provide us with an email address? Or is that not possible with auth0?
