Logging into Bitwarden iOS app with passkey on Yubikey NFC

[SuperGear]

I have created a FIDO2 passkey on my Yubikey and enabled encryption so I can login “passwordless” (with just the Yubikey and no additional factors). While I can successfully login with just this Yubikey’s passkey on the webapp and Chrome extension, the iOS Mobile app doesn’t provide an option to login with a passkey - the only options I get are “Log in with master password”, “Log in with device”, and “Enterprise single sign on”. Does anyone know if this should be possible?

Note, I do have other Yubikeys setup with FIDO2 webauthn passkeys for 2FA on this same account. For those of you who have the above scenario working, does enrolling for 2FA defeat your ability to login passwordless? I am trying to avoid having to remove all my 2FA keys in case the passwordless route is simply not possible with the Bitwarden iOS mobile app.

Thanks!

These are the only two ways currently supported for Login with Passkey.

No, you can use the same Yubikey for 2FA and for Login with Passkey (although you’ll have to enroll the key twice — i.e., if you set up a Yubikey for Login with Passkey, it will not automatically work as a 2FA passkey, and vice versa).
