Unknown device connected to my Google account via Firefox

more options

Hello, I found out that there's a "Nexus 5" device connected to my Google account via Firefox (see screenshot attach for further details). I disconnected, but it keeps connecting again after a few days to my Google account. I've also tried to change my Google and Firefox account passwords, but after a few days, I see this "Nexus 5" in the list of my devices again. That's weird because I do not own any Nexus 5 smartphone, and oddly I also found out the other day that (like in the screenshot) this Nexus 5 was the device I was actually using. I use a Windows machine and 2 Samsung phones.

Any explanation about what's happening?

Thank you

Kind Regards

Hi Marco, that is confusing. Under Nexus 5 it says "This phone" which implies that it's the phone you are using, but where is "Nexus 5" coming from? I think it's a question you will need Google to answer (either in one of its help articles or on its forums).

My phone shows 2 devices, one named "Android" that last connected on April 1 and one with the correct device description which first connected on April 1. I think a system update might have created a bit of confusion, but I don't want to go through the hassle of cleaning it all up right now...
