Plugin to avoid share username in Wordpress

Question

Is there a way to void sharing of username (based on ip address or login at same time in different location) for Wordpress? If there is a plugin just to track IP address and login time, it should be fine too. Thanks

Answer 1

Your question is not very clear. Do you want something like LDAP?

Answer 2

I've not used this, but the IP Logger WordPress plugin looks promising. It has a lot of logging and management features.
