Passwordless Login Overview

Overview

Passwordless authentication refers to any method where users do not need to provide a password to authenticate.

These methods have user interface benefits and can help decrease friction for users looking to log in. No more passwords to remember, or, worse, to forget.

Instead of asking your users to remember a password, with a magic link, send an email, text message, or other communication to the user. Possession of the message proves their identity and authenticates the user.

This method works well when you:

  • know or require your users provide a communication method, such as an email address or phone number
  • want to minimize login friction

WebAuthn Passkeys

Instead of forcing users to remember a password, with WebAuthn passkeys, they can use strong biometric means of authentication. Using a standard protocol called WebAuthn, web and mobile applications can leverage devices such as phones or YubiKeys to authenticate a user.

This method works well when you:

  • know your users use WebAuthn capable browsers
  • want to allow for secure, phishing resistant authentication
  • want to minimize login friction
