any addon to prevent multiples logins?

[hellboy78]

there is any addon that can void multiple logins?
I noted some of my users are sharing their password, and I see multiple IPs into their account.
if there is any addon to void this.

They may very well be on mobile, or using a dynamic IP or proxy, so blocking them from using multiple IP’s is a bad idea.

I know. but into IP list I see different countries. not just cities.
maybe an addon that give me a list of accounts with multiple IPs, so I can check them manually

They may well be using VPNs. That's increasingly common these days for a variety of valid reasons.
