read subdomain session value from DB

I have a LOGIN laravel app under a subdomain, which open login writes to sessions table using session driver as database. The DATA app uses same laravel APP_KEY and as I understand it should be able to see and read the session info set by LOGIN app. Question is how do I read the session info set by LOGIN app in my DATA app.

Session::all() return null, $_COOKIE['id'] return an id that is different from LOGIN app. and my sessions table only have one entry from the LOGIN app.

Thank you
