authentication - Laravel: share session data over multiple domains

Question

I'm building a multi-domain/multi-store ecommerce application in Laravel and would like to keep the user logged in when he or she changes from store to store.

But for as far as I know Laravel's Auth service saves the logged in user in the session and the sessions can't be accessed by other domains.

Is there a way (maybe a package) to achieve this, without leaving my application prone to possible security problems?

Thanks in advance!

Answer 1

1. Capture the session id Session::getId() in Domain A
2. send the captured session id via HTTP POST to Domain B
3. Access the sent session id in domain B $sessionid_from_domainA = $_POST['session_from_A']
4. Set session in domain B Session::setId($sessionid_from_domainA)
5. Start Session in domain B Session::start()
