Login doesn't work cakephp 3

I’m newbie in cakephp, i have finish blog tutorial for my case project, but i have problem with my login doesn’t work. When i debug $users = $this->Auth->identify() function login value has boolean(false). What’s wrong with my source code ?
Here my source code https://github.com/AinulMutaqin/vgmweb.git

your entity file for users should be singular - User.php instead of plural you use - https://github.com/AinulMutaqin/vgmweb/blob/master/src/Model/Entity/Users.php, cake cant use magic setter to hash your password when you add user and thus when you login password doesnt match
