Passkey management with 1Password has been launched as a beta feature. This is expected to enable cross-platform passkey management.

I have confirmed passkey management works using the Chrome extension on macOS.
There are two behaviors that I find remarkable.

  1. local authentication is not executed for registration/authentication with UserVerification=required option.
  2. even if I press the cancel button (❌) during authentication, the login will succeed.

The latter appears to be just a bug.
If UserVerification is skipped due to the former, then the premise of FIDO(w/ UV)’s authentication factor combination (Something You Have + Something You Know/Something You Are) is broken.

Will this behavior continue with the new iOS/Android, which will begin to support it?
