i didn't get any suspicious mails or anything but when i check my access history, i see weird locations. some from different cities in my country and few foreign locations. i've only gave permission to my phone and laptop yet some of these doesn't have any device name.
just to clarify, i have both my device - not my location and no device name - not my location (some ip addresses matches with the ones sent from my device and some don't)
i've already changed my password, i'm wondering, is this behavior normal and is it possible for a device i didn't give permission through
