The technology behind passkeys involves cryptographic keys and standards like FIDO2 and WebAuthn, but users can enhance their security by creating passkeys whenever offered by websites or apps, using face recognition, fingerprints, or PINs. Users can accumulate multiple passkeys for easier sign-in across services. 1Password is set to integrate a new native passkeys plugin API with Windows 11, allowing users to manage passkeys through 1Password while using Windows Hello for authentication. This integration requires the latest version of Windows 11 and the MSIX version of the 1Password app. Users can enable the passkey feature in 1Password and designate it as the system authenticator in Windows settings. Other password managers may also adopt this integration, and Windows is introducing its own passkey sync mechanism through the Microsoft Password Manager in Edge. Passkeys do not replace existing credentials but serve as a secure alternative to usernames and passwords, with some services offering fully passwordless options.
