I gave my old computer to a friend for parts last month and apparently he decided to fix it and gave to someone else and while it was only ever used for wow and YouTube its still marked as a trusted computer to log into my battle net account bypassing my authenticator, to be on safe side could someone do a forced log out of all logins on my account and make it require my authenticator the next time i log in?
Edit i dont have access to my pc at home till tonight
