For AI agents: The complete documentation index is available at /docs/llms.txt. A markdown version of this page is available at /docs/apis/passwordless.md.

This page contains the APIs that are used to authenticate users without passwords using one-time passwords.

You also may find the One-Time Passwords documentation helpful.

Tip

Prior to version 1.41.0, one-time passwords were the only form of passwordless authentication supported by FusionAuth.

Therefore the user interface and API use the term passwordless, even though versions 1.41.0 and beyond support multiple kinds of passwordless authentication, including Passkeys.
