Remember me cookie auth does not work anymore with v16

[LordSimal]

I noticed, that my users have to re-log in rather quickly compared to how they used to in the past.

The Cookie Authenticator is loaded correctly as I see it, but it does not contain the Identifiers it needs.

Adjusting the Cookie Authenticator in the Auth.Authenticators section of the users.php to

'Cookie' => [
    'className' => 'CakeDC/Auth.Cookie',
    'skipTwoFactorVerify' => true,
    'rememberMeField' => 'remember_me',
    'cookie' => [
        'expires' => new \DateTime('+1 month'),
        'httponly' => true,
    ],
    'urlChecker' => 'Authentication.CakeRouter',
    'identifier' => [
        'Authentication.Password' => [
            'fields' => [
                'username' => ['username', 'email'],
                'password' => 'password',
            ],
            'resolver' => [
                'className' => 'Authentication.Orm',
                'finder' => 'active',
            ],
        ],
    ],
],

fixes the problem as it now contains the correct password identifier
