# Passwordless API

Learn about the APIs for magic link passwordless authentication.

This page contains the APIs that are used to authenticate users without passwords using magic links and codes.

You also may find the [Magic Links guide](https://fusionauth.io/docs/lifecycle/authenticate-users/passwordless/magic-links.md) helpful.

> **NOTE:** Prior to version `1.41.0`, magic links and codes 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.
