The exact technical details of session support are not publicly documented, but the appengine-web.xml Reference <https://cloud.google.com/appengine/docs/standard/java/config/appref?hl=fr#sessions_enabled> you pointed to before does say it stores the data on the Datastore with Memcache acting as a speed boost. That is to say it stores it in the same way you should be storing session data if you were to handle it yourself.
And no, at this time this system only supports valid Google accounts, which are gmail.com accounts or a GSuite domain's accounts.
