/**
* Base interface for authentication implementations.
*
* Plugins that provide Auth implementations must provide a class that implements
* this interface. Additionally, an instance of that class must be set in the
* container with the 'Piwik\Auth' key during the
* [Request.initAuthenticationObject](https://developer.matomo.org/api-reference/events#requestinitauthenticationobject)
* event.
*
* Authentication implementations must support authentication via username and
* clear-text password and authentication via username and token auth. They can
* additionally support authentication via username and an MD5 hash of a password. If
* they don't support it, then [formless authentication](https://matomo.org/faq/how-to/faq_30/) will fail.
*
* Derived implementations should favor authenticating by password over authenticating
* by token auth. That is to say, if a token auth and a password are set, password
* authentication should be used.
*
* ### Examples
*
* **How an Auth implementation will be used**
*
* // authenticating by password
* $auth = StaticContainer::get('Piwik\Auth');
* $auth->setLogin('user');
* $auth->setPassword('password');
* $result = $auth->authenticate();
*
* // authenticating by token auth
* $auth = StaticContainer::get('Piwik\Auth');
* $auth->setLogin('user');
* $auth->setTokenAuth('...');
* $result = $auth->authenticate();
*
* @api

* hash of the token auth in the session cookie. You can calculate the token auth hash using the
* {@link \Piwik\Plugins\Login\SessionInitializer::getHashTokenAuth()} method.
