Question: I want to change the default login validation error message like:

```
Username & Password doesn't match

```

instead of

```
these credentials do not match our records

```

How to do this ?

Answer: 
You can change this message to another one in this file:

```
resources/lang/en/auth.php

```

This is the line:

```
'failed' => 'These credentials do not match our records.',

```
do one thing make new file message.php in lang folder then enter the error message in that and access in the controller and where you want to use like this 
in Authonticateduser.php

```
protected function sendLoginResponse(Request $request) {
    $request->session()->regenerate();
    $this->clearLoginAttempts($request);
    return $this->authenticated($request, $this->guard()->user())
            ? : redirect()->intended($this->redirectPath())->with('status', Lang::get('messege.login_success'));
}

```

and you get the perfect mesege you want instead of system mesege and without any change in default message.
