Access two Gmail accounts at once in the same browser

I have a couple different Gmail addresses that I use for different purposes. Historically, Google Accounts – including Gmail accounts — have only let people access one account at a time per browser, so using both accounts has been a bit inconvenient. I’ve either had to sign out and sign back in, use a second browser for my second account, or use a Chrome incognito window. And I'm not alone; lots of people have asked us for a better way to use multiple accounts at once in the same browser.

Now, you can visit google.com/accounts and click the link next to "Multiple sign-in." After you sign into your first account, you can sign in with up to two additional accounts from the new accounts menu in the upper right hand corner of Gmail, then easily toggle back and forth between them. You can even open multiple Gmail tabs — one for each of your accounts.
