Google has been doing this a lot to me lately. It’s almost always on my phone though. For some reason, every so often my phone thinks it’s in another state and Google sends me an email saying to change my password.
The first time I got that email I was on vacation and had a hard time changing my password but I did. It’s happened a few times in the last two years or so, now I just ignore it because it always says it’s my phone that’s got my password. I’ve had it do the same thing on my laptop as well, it just starts telling me that someone has my password and sends me a bunch of emails telling me to change it.
I think Google, and my banks too, are starting to get too excited about protection. I wouldn’t be surprised if it was some sort of glitch.
