I have a weekly meeting video call, during which I open my meeting notes in Google Docs. For the past few weeks, my Google login has expired in the middle of the meetings - it's annoying. Apparently, Google's login session has a one-week lifetime; therefore, it expires roughly the same time every week.
Maybe login systems should suggest users to re-login, for example, 1 day before the login session expires. Perhaps also show the login session remaining time to the users.
