Fido2 Passwordless Login

[quexten]

Upstream recently merged passwordless fido2 login in the backend and frontend (just on master for now). Creating this discussion to see what's required for the feature to be implemented.

Client:
bitwarden/clients#6798

Server:
bitwarden/server#3467
bitwarden/server#3361
bitwarden/server#2915
bitwarden/server#2885

As far as I can tell it should mostly be implementing a few new API endpoints and creating the database queries.

also another minor client PR:
#6861

[ReLoia]

any update on this discussion? Is there any stated reason on why we can't login without a password?

Because t that feature isn't part of Vaultwarden yet. It's that simpel.

There is a PR open for it. #5929
