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.

## Magic Links and One Time Passwords[#](#magic-links-and-one-time-passwords)

Instead of asking your users to remember a password, you can use magic links or one-time passwords (OTP). This authentication method sends an email or message to the user that allows them to log in without entering a password.

Possession of the message proves the user's identity and authenticates them. This method uses either a clickable link (aka a magic link) or a delivered one-time password (OTP), like `000000`.

This method works well when you:

*   have a way to message your users, such as an email address, phone number, or Facebook account
*   want to minimize login friction

## WebAuthn and Passkeys[#](#webauthn-and-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
