pass keys in what context?

Like when you have Two-factor authentication enabled and instead of using an authenticator app. You use your touch id on your pc etc. Like discord has Security keys

Railway does support 2FA https://railway.app/account/security

Yea but "Pass keys" , when 2FA is enabled. Here is an example: https://i.ibb.co/Hxkrz6S/image.png

The 2FA that is available to enable from the link i provided is the only 2FA they support

Alright, thanks for the help!
