A relative of mine is currently in a different country and asked me for help as they can't log into their own Gmail account from there. Gmail considers the login attempt suspicious, almost certainly because of the location, and blocks it.
I'm at a non-suspicious location and can still access the account and I can see that Google sent a mail about the suspicious attempt and displays a notification bar warning about it. What I can't see is any way to tell Google that it shouldn't block logins from that location.
How can I prevent Gmail from locking me out like this in a different country? Is there a way to notify it of upcoming trips so that it doesn't consider it suspicious? And is there any way to unlock Gmail once you're in a country it considers suspicious, or do you have to wait until you're home again?
