Our application uses a combination of an in-house authentication scheme as well as Auth0 to login users with enterprise accounts. I would like to use the Identifier-First option for Universal Login with Home Realm Discovery for these enterprise customers. However, when we don’t match the user’s entered domain, I would like to redirect back to our native login. Is this possible?
Welcome to the Auth0 Community!
There isn’t currently a simple way to tap into the identifier part of the login flow. There are plans for a trigger that sounds like would cover this use case.
