Possible to link two auth0 email based identities and have them both authenticate using same password?
Other issue is that username aliases don’t usually start out as a second existing email/password account you can link to a primary identity. Instead you have one auth0 email/password account then you’d like to add a second email to that account as a username alias. How to do this? Create a temp user with a dummy password and then link to it? A bit of a hack.
