my gf left her fb logged in on my phone and i peeked at something real quick. now im paranoid shell get a login alert about a new device. does fb actually notify you when someone signs in from another phone?
Yeah Facebook does send login notifications, but here’s the thing - if her account was already logged in on your phone, you didn’t trigger a new login. You’d only get the alert if you actually typed in credentials on a fresh session.
So you’re probably fine, but maybe worth asking yourself why you were digging around in the first place, lol.
