How to use another field for authentication in Laravel?

Question

In the manual I can read:

By default, Laravel uses the email field for authentication. If you would like to customize this, you may define a username method on your LoginController

However in my case I would like to use the unique_id field which is provided by my company to authenticate my user. This field is not a username so I feel bad about using the username() method to get this. Is there another way to tell Laravel Authentication to use something else than email to authentify my users?

You still define the username() method, you just make it return unique_id instead of username. That method simply tells the auth what column to use if you don't plan on using the default. — Tim Lewis

Yeah, I agree that the username() method's name is quite unfortunate, but that's the way to go. — Robo Robok

But still if I manually call username I will get a confused result which is not the username but an id. — nowox

You can override validateLogin and credentials methods in your Auth/LoginController

protected function validateLogin(Request $request)
{
    $request->validate([
        'unique_id' => 'required',
        'password' => 'required|string',
    ]);
}

protected function credentials(Request $request)
{
    return array_merge($request->only('unique_id', 'password'));
}

You must override username() method too.

Ignore the fact that the method is called username() and go for it.

You can overwrite username() method in App\Http\Controllers\Auth\LoginController::class like this:

/**
* Get the login username to be used by the controller
* You Username will be User $unique_id
*/
public function username()
{
    return 'unique_id'
}
