 Access Tokens can be used to authenticate users for your own site, or when allowing third-party developers to access your API. When making requests using access tokens, the token should be included in the `Authorization` header as a `Bearer` token.
 
-To issue tokens for users, the `UserModel` must use the `CodeIgniter\Shield\Authentication\Traits\HasAccessTokens` trait. The `UserModel` that ships with Shield already uses this trait.
-
-```php
-use CodeIgniter\Shield\Authentication\Traits\HasAccessTokens
-use CodeIgniter\Model;
-
-class UserModel extneds Model
-{
-    use HasAccessTokens;
-}
-```
-
 Tokens are issued with the `generateAccessToken()` method on the user. This returns a `CodeIgniter\Shield\Entities\AccessToken` instance. Tokens are hashed using a SHA-256 algorithm before being saved to the database. The access token returned when you generate it will include a `raw_token` field that contains the plain-text, un-hashed, token. You should display this to your user at once so they have a chance to copy it somewhere safe, as this is the only time this will be available. After this request, there is no way to get the raw token.
 
 The `generateAccessToken` method requires a name for the token. These are free strings and are often used to identify the user/device the token was generated from, like 'Johns MacBook Air'.

-When the filter runs, it checks the `Authorization` header for a `Bearer` value that has the raw token. It then looks hashes the raw token and looks it up in the database. Once found, it can determine the correct user, which will then be available through an `auth()->user()` call.

 Note: Currently only a single scope can be used on a route filter. If multiple scopes are passed in, only the first one is checked.
