Push-based 2FA on Auth

[DaFlowah]

As for the upcoming feature of the just-released Bitwarden Authenticator (see roadmap at the bottom), support for Push-based 2FA would be amazing: you get a notification in the app and you can just approve or deny it.
Similarly as what happens with Google notifications.
This would make MFA more accessible to the "average user".
I guess this could work on both mobile and desktop (if doable).

EDIT: just found out that also 2FAS has something similar.

Wouldn't that require Firebase/whatever Apple uses as a notification server? I don't think that'd be ideal.
