Passwordless Authentication and Passkeys: How FIDO2 Enables Secure Login
Password-based authentication is slowly disappearing from the login experience in 2026. Instead, users increasingly authenticate with a fingerprint, device PIN, or security key without typing a password. This is where passwordless authentication and passkeys come in. Built on FIDO2 and WebAuthn, passkeys use cryptographic credentials to make passwordless login simpler for users while reducing exposure to phishing and credential theft. But passkeys are only one part of the picture.
