we are creating a POC to see if we can migrate our users without much disruption to business. Our userbase has same db for multiple tenants and userName can be duplicate across tenant . At present we idenitfy tenant of user by tenantid and use that during authentication.
we are looking at way to customize the universal login screen which wil allow user to login with his existing username and want to add tenantId to the username entered to uniquely idetify that user in Auth0 . Is it possible to do that with js.
I could find the on signin submit event but am not able to identify where auth0 stores username while sending it to login ?
Do let us know if there is a better way to achieve this ?
