Memberium can be configured to keep a record of login sessions for each user. The system collects the login time, IP address, username, and location (based on the IP).
How to Enable
Enable the Login Log by going to Memberium > Settings > Login:
If you enable IP Address login limits, then the login log will be automatically enabled regardless of the setting above. Memberium uses the login log to track how many IP addresses have been logged in for each user account.
The data is stored in a database table that you can access through normal tools, such as phpMyAdmin.
