# NONE (Public Client) Flow

For applications that have the `tokenEndpointAuthMethod` property set to `NONE`, you do not authenticate the token endpoint. The request requires the `client_id` property value in the request body and does not require an `Authorization` header. This method is used with PKCE authorization code flows for use with public clients.

## What you'll do

You will send an authorization request to start the workflow.

* POST request to the authorize endpoint.

* POST request to submit the user's username and password.

* POST request to get the access token.
