What Is Passwordless Authentication?

Passwordless authentication is exactly what it sounds like: authentication methods that do not require a password. This could mean passkeys, authenticating credentials through device biometrics, or hardware token security keys.

Passwordless authentication means users don’t need to create, remember, or otherwise deal with password management. It also means that your business isn’t relying on often-weak passwords (1234, anybody?) to verify user identity and protect your data.

A Better User Experience for Sign In

78% of people say they’ve had to reset their password in the last three months. 30% find resetting passwords stressful. Passwordless authentication makes signing in easy, secure, and stress-free. The passwordless experience lets you simplify your authentication process while removing vulnerabilities related to password reuse, credential stuffing, and phishing attacks.

Boost Security with FIDO2 Standards

Passwords play a huge role in data breaches. Credential theft is one of the most common forms of cybercrime. By eliminating passwords, you also eliminate an attack vector. Passwordless authentication is based on FIDO2 Webauthn standards using private key and public key pairs. Implementing passwordless authentication through hardware tokens, facial recognition, or other biometric authentication methods native on a user’s device means that password-based authentication is a thing of the past.
