Your Gmail is now a lot more secure
Your email account can contain a lot of personal information, from bank alerts to love letters. Email that, I'm sure, you don't always want other people to see. We understand how important your Gmail accounts are to you, so we're adding a new layer of information and control. With this new feature, you can now track your recent sessions and you can also sign yourself out remotely.
If you are anything like me, you probably sign in to Gmail from multiple computers. I, for example, occasionally sign into my Gmail account from a friend's house when I need to check an important email. Usually I remember to sign out, but every once in a while I wonder if I really did. Now I no longer have to wonder.
At the bottom of your inbox, you'll see information about the time of the last activity on your account and whether it's still open in another location.
