Restrict only one access by account

[epsilon2138]

I would like to know how to restrict access a more than one access with same account. I have seen than one can access with the account from many locations. On my project i need not allow share same account.

Thanks and I would be very grateful for any help.

Hi epsilon,
Do you mean you want to restrict access based on a geographical location.
i.e. the user can only log in if he is located in a specific city or tries to log in to the account from a specific IP address?
