Passwordless Authentication Unlocks Stronger, More Convenient Security Passwordless authentication is just what it sounds like: it verifies user identities without passwords or any other information that users need to memorize. Passwordless enables authentication with less burdensome, more secure methods—such as one-time passwords (OTPs), passkeys, app-based options (like push to approve), and biometrics. Passwordless authentication is also critical in building organizations’ anti-phishing capabilities, because it reduces the use of password-based credentials that bad actors can compromise to carry out phishing attacks.
