# CIAM-Passwordless-Protect-Magic-Link-Authentication-Subflow

The CIAM-Passwordless-Protect-Magic-Link-Authentication-Subflow lets existing users authenticate using a link sent to the email address that's associated with their account.

## Purpose

The **CIAM-Passwordless-Protect-Magic-Link-Authentication-Subflow** presents users with the option to send a magic link to the email address associated with their account. After the link is sent, the flow checks the status of the link. If the link is clicked, the flow authenticates the user. If the link expires, the flow presents an error message. The magic link expires after 2 minutes.

## Structure

Diagram of the structure, as described below.

This flow is divided into sections using teleport nodes:

* **Display Magic Link Form**

  Uses a PingOne node to look up the user, then presents an HTML form from which the user can send a magic link. The flow then simultaneously progresses to the **Create Challenge and Send Email** and **Challenge Acceptance By The User** sections.

* **Create Challenge and Send Email**

  Uses a PingOne node to send a magic link email. The flow then progresses to the **Display Magic Link Polling And Check For Challenge Status** section.

* **Challenge Acceptance By The User**

  Checks the challenge status and displays a success message if the magic link is clicked and an error message if the magic link times out.

* **Display Magic Link Polling And Check For Challenge Status**

  Displays a custom HTML template directing users to click the magic link. When the challenge is approved, the flow progresses to the **Show Success Message** section.

* **Show Success Message**

  Displays one of two success forms depending on whether the user has any other MFA devices. The flow then progresses to the **Return Success** section.

* **Challenge Expiration**

  Denies the challenge if the magic link expires. The flow then progresses to the **Return Error** section.

* **Return Success**

  Sends a success JSON response, indicating that the flow has completed successfully.

* **Return Error**

  Sends an error JSON response, indicating that the flow completed unsuccessfully.
