You wouldn’t exactly want your co-workers or client to know your personal email accounts, now would you? Especially if they show a side of you that you wouldn’t want them to know. Well, Google is hoping to come to your rescue with a new “account awareness” feature. This new account switching tool is coming to Docs, Slides, and Sheets. It’s still accessible at the top right corner of your account. But instead of showing you the list of accounts you have, you see a small box with the text “You’re currently signed in as [x].” And if you want to see your other accounts, you can click on “Change account” at the bottom of the pop-up.
All G Suite editions will have this feature on by default. Those with the rapid release domains will get the new switcher in 15 days or less, while those with scheduled release domains will get this later this month.
