Laravel auth using GET method

In my laravel project, i use zizaco/entrust for role base authentication. I have two role admin and user. Now i want user can loginin two process. One process to normal login system in laravel (It's working well) and another process to use get method like
http://myproject/login?username=username&password=password when user set this url, then call login route where email & password get from url's username & password and after matching data login user successfully. Now i have to question that how can i handle 2nd process to login from user. Any technique can i follow?
