Authenticate user through email using Sentinel

Question

Is there any way to authenticate a user via email/link/code in Cartalyst Sentinel?

I'm building a simple user registration in Laravel 5.1 which sends a activation email after sign up. By clicking the link, I'd like to activate and authenticate the user in the same action, but I haven't managed to do that.

The only way seems to be passing the credentials (Sentinel::($credentials)), but I just have the $code and $id, needed for the activation, and it asks for the password (which would be a little insecure the send via email, by the way).

Is there any way to do this? Thanks in advance!

If you have or can retrieve the user object (which you need to complete the users activation anyway), then you can use login() to login a user without their credentials.

$user = Sentinel::findById($id);

Sentinel::login($user);

The whole process should look something like this:

$user = Sentinel::findById($id);

if ( ! Activation::complete($user, $activationCode))
{
    // ERROR - Invalid or expired activation code.
}

// Login the User
Sentinel::login($user);

// Redirect to where you want to take them
