Choose something that will be harder for others to guess.', 'jetpack' ), 'required' => true, ), ) ); $tests = apply_filters( 'password_checker_tests', $tests ); ``` Test a password: ```php use Automattic\Jetpack\Password_Checker; $user = new WP_User( 1 ); $password_checker = new Password_Checker( $user ); $password_checker->test( '123', true ); ``` ## Using this package in your WordPress plugin If you plan on using this package in your WordPress plugin, we would recommend that you use [Jetpack Autoloader](https://packagist.org/packages/automattic/jetpack-autoloader) as your autoloader.
