Gmail automatic logout due to multiple logins during one session

gmail

My suspicion is with my Gmail account, I fear it has been hacked because I was logged in and randomly received a pop-up notification stating a second login has been detected from the same session. This struck me as odd because in the list of IP addresses in Gmail's recent activity, only my IP is listed and the only other device that has my username/password stored is my smartphone which auto syncs with my account but it was turned off at the time.

Has anyone ever seen this before, and are there any preventative measures I can take to better secure my account with Google?

I have not seen this, but I strongly recommend adding 2-factor authentication to your Gmail account to make it more secure.

It will add a second "password" used to approve new devices you login with, via a phone call or text message.
