Passwordless sign-in credentials based on FIDO standards that use a device-held private key released after biometric, PIN or pattern verification.

Passkeys cut account takeover from phishing and password reuse while reducing login friction and reset requests, which matters for customer portals and for staff access to email, CRM and advertising accounts.

A B2B portal offers passkey registration after login, keeps password plus authenticator app codes as a fallback for six months, and once 70% of active users sign in with passkeys, removes SMS codes as a recovery option.

Account recovery remains a weak point if fallback methods can be phished. Synced passkeys depend on the security of the provider account, and support on older devices, shared workstations and some enterprise setups is still uneven.

Passkeys implement FIDO2: the W3C Web Authentication (WebAuthn) API in browsers and the Client to Authenticator Protocol (CTAP). At registration the authenticator creates a key pair scoped to the site's relying party ID, and the server stores only the public key. At sign-in it signs a server challenge after local user verification. Synced passkeys move between devices through a credential manager, while device-bound ones stay on one authenticator. They can replace Multi-Factor Authentication (MFA) based on passwords and codes.
