I'll make this short. L925 T mo. Internet sharing enabled. Shows 2/8 connections on my phone. One is my PC. Don't have a clue what the other is. How do you view who is connected? Or did we all fail to ask for this ability and now anyone could share my phone data and I'd never find out? Lol

Maybe change the password and only add that PC?

I remember noticing the odd 2/8 on my 920, but then I realized I paired the random Android in my backpack to my phone too along with my PC.

Maybe, If you have Windows 8.1/10, you had enabled the "Sync WiFi Password" option, and there is another computer/phone with your Outlook account connecting to your phone.
I recommend to use the Bluetooth Internet Sharing (If your computer has bluetoth of course). It's most fastest than WiFi sharing, and, at least for me, the phone doesn't overheat.
Only the devices that you have added as Bluetooth devices on your phone can connect
