Learn about the APIs for magic link passwordless authentication.

# Passwordless API

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](/docs/lifecycle/authenticate-users/passwordless/magic-links) helpful.

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.

Use the following APIs to manage Passwordless authentication:

| Operation | Method | Endpoint |
| --- | --- | --- |
| [Start Passwordless Login](/docs/apis/passwordless/start-passwordless-login) | `POST` | `/api/passwordless/start` |
| [Send Passwordless Login](/docs/apis/passwordless/send-passwordless-login) | `POST` | `/api/passwordless/send` |
| [Complete a Passwordless Login](/docs/apis/passwordless/complete-a-passwordless-login) | `POST` | `/api/passwordless/login` |
