# Relevant API Endpoints for Passwordless Connections

When working with Passwordless Connections, the following API endpoints will be helpful to you.

## Authentication API

### POST /passwordless/start

The [POST /passwordless/start](/api/authentication#get-code-or-link) endpoint can be called to begin the Passwordless authentication process. Depending on the parameters provided to the endpoint, Auth0 begins the user verification process by sending one of the following:

## Management API

The Management API features several endpoints designed to help you manage your connections, including your Passwordless ones.

To call any of the Management API endpoints, you will need to [obtain an Access Token](/api/management/v2/tokens).

### Get all connections

The [GET /api/v2/connections](/api/management/v2#!/Connections/get_connections) endpoint retrieves all connections for your tenant that match the parameters you provide. You can use this endpoint to obtain the connection ID for your Passwordless connection (indicated by the `strategy = sms` parameter), which you'll need to make changes to the connection.

### Delete a connection

### Delete a user from a connection
