# AUTH

Our phone also offers the capability to create custom applications utilizing our built-in **Auth System**. This grants access to the full **Account Manager**, enabling seamless account creation and management. To learn more details, please proceed to the next page.

You can find an example of a custom application with the built-in authenticator on our GitHub, in the "auth" branch of our [boilerplate](https://github.com/17movement-net/17mov_Phone_app_boilerplate/tree/auth)
