Check whether password is correct or not in Laravel

As Hiren has mentioned you can use the default registered hasher as that is passed to the specific UserProvider used. The default is Illuminate\Hashing\BcryptHasher.

You can use it a couple of ways:

1. Out of the container

$user = User::find($id);
$hasher = app('hash');
if ($hasher->check('passwordToCheck', $user->password)) {
    // Success
}

2. Using the Facade

$user = User::find($id);
if (Hash::check('passwordToCheck', $user->password)) {
    // Success
}

3. Out of interest using the generic php function password_verify also works. However that works because the default hashing algorithm it uses is bcrypt.

if (password_verify('passwordToCheck', $user->password)) {
    // Success
}
