Contao 4 online helper bundle
Contao 4.9+ helper bundle
The hooks "postLogin", "postLogout" and "postAuthenticate" are used to register the online status of the users (FE/BE).
For this purpose, the ID, the time stamp and a hash (hash_hmac,sha256) are created in the table tl_online_session.
This Helper Bundle is still under development and will be used in the future by the bundles "LastLogin" and "BE_User_Online".
