Description

I could only find that hanko supports registering users with email as their identifier. We are using phone numbers in our app and registering a passkey once OTP verified. We want to use Hanko but cannot.

Describe your ideal solution

Ability to use phone number or generic field (username) instead of email for sign-in. I am not sure whether the deficiency is in hanko-elements or hanko.

Workarounds or alternatives

We could use passkey-server and a custom auth solution but we would like an all-in-one product like Hanko backend.

Hanko supports usernames, but not yet phone numbers. You can theoretically use a phone number as a username, but we do not yet have the logic to send SMS or connect an SMS provider for the OTP.

We have plans to add sms providers at some point, but it's not on the immediate roadmap.
