Which authentication method removes the use of passwords entirely?

Passwordless authentication removes the need for passwords by using alternative verification methods like biometrics (fingerprint, facial recognition), FIDO2 security keys, or magic links sent to trusted devices. This enhances security by eliminating common password-related vulnerabilities such as phishing, brute-force attacks, and credential stuffing. MFA (Multi-Factor Authentication) adds a second verification step but still typically relies on a password as the first factor. RBAC (Role-Based Access Control) is an authorization method, not an authentication method, and defines what a user can do after they've been authenticated. Basic authentication is a legacy method that uses a username and password, often sent in plain text, making it highly insecure.
