  2. 9 core/modules/user/user.api.php \hook_user_format_name_alter()

Alter the username that is displayed for a user.

Called by $account->getDisplayName() to allow modules to alter the username that is displayed. Can be used to ensure user privacy in situations where $account->getDisplayName() is too revealing. This hook is invoked both for user entities and the anonymous user session object.

Parameters

string|Drupal\Component\Render\MarkupInterface $name: The username that is displayed for a user. If a hook implementation changes this to an object implementing MarkupInterface it is the responsibility of the implementation to ensure the user's name is escaped properly. String values will be autoescaped.

\Drupal\Core\Session\AccountInterface $account: The object on which the operation is being performed. This object may be a user entity. If the object is an implementation of UserInterface you can use instanceof operator before accessing user entity methods. For example:

if ($account instanceof UserInterface) {

  // Access user entity methods.
}
