Why do you need to manage two tables to maintain two types of users?
Isn't that easy to maintain users' roles and store all the uses in one table? I will reduce your complexity and easy to manage the code. There are some packages already for that you don't need to reinvent the wheel!
If you are forced to maintain two tables, then you need to write custom authentication for admin users. I am sure you will get many tutorials for making custom authentication in Laravel.
