# Authentication

## Register a new user.

This route lets you create new users.

#### Usage

```js
$.ajax({
  type: 'POST',
  url: 'http://localhost:1337/auth/local/register',
  data: {
    username: 'Strapi user'
    email: 'user@strapi.io',
    password: 'strapiPassword'
  },
  done: function(auth) {
    console.log('Well done!');
    console.log('User profile', auth.user);
    console.log('User token', auth.jwt);
  },
  fail: function(error) {
    console.log('An error occurred:', error);
  }
});
```

## Login.

This route lets you log your users in  by getting an authentication token.

#### Usage

- The `identifier` param can either be an email or a username.

```js
$.ajax({
  type: 'POST',
  url: 'http://localhost:1337/auth/local',
  data: {
    identifier: 'user@strapi.io',
    password: 'strapiPassword'
  },
  done: function(auth) {
    console.log('Well done!');
    console.log('User profile', auth.user);
    console.log('User token', auth.jwt);
  },
  fail: function(error) {
    console.log('An error occurred:', error);
  }
});
```

## Use your token to be identified as a user.

By default, each API request is identified as `guest` role (see permissions of `guest`'s role in your admin dashboard). To make a request as a user, you have to set the `Authorization` token in your request headers. You receive a 401 error if you are not authorized to make this request or if your authorization header is not correct.

#### Usage

- The `token` variable is the `data.jwt` received when login in or registering.

```js
$.ajax({
  type: 'GET',
  url: 'http://localhost:1337/article',
  headers: {
    Authorization: `Bearer ${token}`
  },
  done: function(data) {
    console.log('Your data', data);
  },
  fail: function(error) {
    console.log('An error occurred:', error);
  }
});
```

## Send forgot password request.

This action sends an email to a user with the link of you reset password page. This link contains an URL param `code` which is required to reset user password.

#### Usage

- `email` is your user email.
- `url` is the url link that user will receive.

```js
$.ajax({
  type: 'POST',
  url: 'http://localhost:1337/auth/forgot-password',
  data: {
    email: 'user@strapi.io'
    url: 'http://mon-site.com/rest-password'
  },
  done: function() {
    console.log('Your user received an email');
  },
  fail: function(error) {
    console.log('An error occurred:', error);
  }
});
```

> Received link url format http://mon-site.com/rest-password?code=privateCode

## Reset user password.

This action will reset the user password.

#### Usage

- `code` is the url params received from the email link (see forgot password)

```js
$.ajax({
  type: 'POST',
  url: 'http://localhost:1337/auth/reset-password',
  data: {
    code: 'privateCode'
    password: 'myNewPassword'
    passwordConfirmation: 'myNewPassword'
  },
  done: function() {
    console.log('Your user password is reset');
  },

    console.log('An error occurred:', error);
  }
});
```
