Issue in Authenticating the user: laravel 5.1

I am using in-built Registration and Login code in Laravel 5.1

What I am doing ?

I did the registration and credentials are being saved successfully.

What's the problem ?

When I try to do the login, it says "These credentials do not match our records."

In postLogin Method , I saw the code : $credentials = $this->getCredentials($request); and when I printed values in $credentials and found that the Password value is plain text.

May be that's the reason the below line when executes always says User not found

if (Auth::attempt($credentials, $request->has('remember'))) {

Please suggest me the path
