Passkey and 1Password

Hello lodaka! 👋

Thanks for the question! You can only save one passkey per Login item in 1Password. Once you save a passkey for an account in 1Password, that passkey will be available for sign in on all of your devices.

Unlike passwords, you can’t create a weak passkey. Passkeys are generated by your device using a public-private key pair, which makes them strong and unique by default. Passkeys can’t be phished like a traditional password because the underlying private key never leaves 1Password – this also makes them resistant to social engineering scams.

Two-factor authentication, using technologies like hardware security keys, was designed to add an additional layer of protection to passwords against phishing. Passkeys are already resistant to phishing and can be considered to have the same level of security as a password plus two-factor authentication, with a lot less friction. Thus, there's no need to save a security key as another passkey if you're already using a passkey for authentication.
