Simple login and user management system

We need a simple log in and user management system with the following functionality: Admin - Admin log in. Admin log out. Admin can add/edit/delete accounts. Accounts consist of username, password and email. Password should be encrypted when saved to the dB. Admin can assign user to one or more projects. Users - Log in Log out No registration is needed. Once logged in, the user can be taken to a page that says 'You are now logged in'. Technical details - The dB log in credentials need to be kept in its own PHP file and loaded with an 'include_once' call. dB calls need to use MySQLI. Design is not required. However, basic CSS tags should be used for the basic layout.
