Step 1) Install Laravel Authentication Package
composer require laravel/ui "^1.0" --dev php artisan ui vue --auth
Step 2) Make Appropriate Changes to the User Model.
Step 3) Get Rid of Authentication Controller generated by Laravel.
Step 4) Create your own controller 1 for Login and 1 for Adding User
Step 5) You can use custom form requests to separate the Logic from the controller, for instance validation rules etc can be stored in the Form Request.
For E.g
php artisan make:request StoreUserRequest
Now you can pass StoreUserRequest to the Controller. For E.g
public function StoreUser(StoreUserRequest $request)
Step 5) Remember to Hash the Password before storing in the DB
$password = Hash::make($request->password);
Step 6) Use Auth::attempt(['username']=>'WHATEVER OR $request->username','password'=>$request->password) to Check for Valid User..
Step 7) Auth::User() should return the User anywhere in Views or Controller..
