The recent addition of the PRF (Pseudo-Random Function) extension to FIDO, which enables symmetric encryption, is indeed a key milestone we were waiting for. With this in place, we are actively working toward adding USB security key / FIDO2 support, including YubiKeys, in Enpass.
Our goal is to support hardware keys both as a master-passwordless authentication method and as a multi-factor authentication (MFA) option. While we donโt have an exact release date to share yet, our current plan is to introduce this support in Q2 of this year.
We appreciate your patience and continued interest.
