Hello community!

At the moment we have the current solution:

- regular database connection that requires username for signup
- login with username or email attr

We are planning to:

- Disable authentication for username attr and leave only email as valid attr for login

what would be the best approach to achieve this? I can not find a clear way to do it on docs/community old post

In addition:

- Is it possible to know during post-login actions if the user logged in with username or email for authentication?

Thanks in advance!!!

Hello @ezequiel.sandoval,

Welcome to the Community! I’m not sure if this answers your question but if you disable usernames, users who already had a username can continue to log in with their username.

Yes, I tried that approach and i saw that behaviour, so, in order to “remove” username login we should disable this and also delete that attribute from users entries?

I would say yes but I’m not sure you can delete the username with the API in its current state. If you manage to do so, please let me know!
