Prevent several users on the same account

[Michael Ohana]

Hello, 

Let me first explain the context : I own a private forum, which content is exclusively reserved to the members who followed the formation I purpose in real life. So it is very important to me that the content remains exclusively for the people I allowed. 

Here comes the issue : some dishonest people give their Ids and passwords to their friends, so that they can also access my forum whereas they've never been allowed to. It is dangerous for my business so I would like to know if there is an option to prevent several people to connect on the same account. (maybe linked to IP adress I don't know)

Kind regards.
