Cannot login user and admin user to the main website

Building a django project and successfully done the registration, login, logout and activate views, the registration is working because a user get a link sent to their email after they signup but I’m having errors saying invalid credentials when I try to login with that created account also same with trying to login with the admin password and email address, can only login to the admin panel. Here is the codes.
