+//! API authentication.
+//!
+//! The API uses a [bearer token authentication scheme](https://datatracker.ietf.org/doc/html/rfc6750).
+//!
+//! API clients must have an account on the website to be able to use the API.
+//!
+//! # Authentication flow
+//!
+//! - [Registration](#registration)
+//! - [Login](#login)
+//! - [Using the token](#using-the-token)
+//!
+//! ## Registration
+//!
+//! ```bash
+//! curl \
+//! --header "Content-Type: application/json" \
+//! --request POST \
+//! --data '{"username":"indexadmin","email":"indexadmin@torrust.com","password":"BenoitMandelbrot1924","confirm_password":"BenoitMandelbrot1924"}' \
+//! http://127.0.0.1:3000/v1/user/register
+//! ```
+//!
+//! **NOTICE**: The first user is automatically an administrator. Currently,
+//! there is no way to change this. There is one administrator per instance.
+//! And you cannot delete the administrator account or make another user an
+//! administrator. For testing purposes, you can create a new administrator
+//! account by creating a new user and then manually changing the `administrator`
+//! field in the `torrust_users` table to `1`.
+//!
+//! ## Login
+//!
+//! ```bash
+//! curl \
+//! --header "Content-Type: application/json" \
+//! --request POST \
+//! --data '{"login":"indexadmin","password":"BenoitMandelbrot1924"}' \
+//! http://127.0.0.1:3000/v1/user/login
+//! ```
+//!
+//! **Response**
+//!
+//! ```json
+//! {
+//! "data":{
+//! "token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyIjp7InVzZXJfaWQiOjEsInVzZXJuYW1lIjoiaW5kZXhhZG1pbiIsImFkbWluaXN0cmF0b3IiOnRydWV9LCJleHAiOjE2ODYyMTU3ODh9.4k8ty27DiWwOk4WVcYEhIrAndhpXMRWnLZ3i_HlJnvI",
+//! "username":"indexadmin",
+//! "admin":true
+//! }
+//! }
+//! ```
+//!
+//! **NOTICE**: The token is valid for 2 weeks (`1_209_600` seconds). After that,
+//! you will have to renew the token.
+//!
+//! **NOTICE**: The token is associated with the user role. If you change the
+//! user's role, you will have to log in again to get a new token with the new
+//! role.
+//!
+//! ## Using the token
+//!
+//! Some endpoints require authentication. To use the token, you must add the
+//! `Authorization` header to your request. For example, if you want to add a
+//! new category, you must do the following:
+//!
+//! ```bash
+//! curl \
+//! --header "Content-Type: application/json" \
+//! --header "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyIjp7InVzZXJfaWQiOjEsInVzZXJuYW1lIjoiaW5kZXhhZG1pbiIsImFkbWluaXN0cmF0b3IiOnRydWV9LCJleHAiOjE2ODYyMTU3ODh9.4k8ty27DiWwOk4WVcYEhIrAndhpXMRWnLZ3i_HlJnvI" \
