Restrict Same User from Logging in Simultaneously

Hi All,
Is there a way or plugin to restrict one user from logging in simultaneously.

Example:
A registered user called John is currently logged in, he gave his username and password to his friend. Then his friend also log in. This means John has a double login currently.

I want to do something like John currently logged in and anyone who try to login using the same username while John has already login to fail. That means only one instance of login by the same username is allow.

Currently WordPress allow 2 login instance using the same username.

Please advise.

Thanks in advance.
