This feature has been available for almost a year but many people still have not enabled it. This is a good time to review its use, for a couple of reasons:
- If you are a Google Apps user who wants to experiment with Google Plus, you will need to switch to a personal Gmail account to do so.
- Now that most Google Apps accounts can be used to sign in to other Google services, it is no longer possible to keep your Google Apps account and personal Gmail account open at the same time in the same browser.
Using the multiple accounts feature allows you to switch quickly back and forth between accounts. Here’s how to set it up:
- Sign in using your personal Gmail account and click on your email address (or photo, if you’ve added one) on the right side of the menu bar.
- Select “Account settings”.

- Select the “Edit” link next to “Multiple sign-in”.

- On the following screen, select the “Yes” radio button and check all the boxes to indicate that you know what you’re doing.
- Return to Gmail and reload the page.
- Click again on your address or photo in the menu bar.
- Click on “Switch accounts” in the lower right of the pop-up window.
- Click on “Sign in to another account”.

- Enter the username and password for another Google account. The second account will load in a new tab.
- To verify that you can switch between accounts, click on your address or photo in the menu bar.
Click on “Switch accounts”.
Note that both accounts are now shown, with a green check mark next to the current account.

I recommend that you keep only one tab open and use “Switch accounts” to move between different Google accounts. Otherwise, it gets confusing as to which account you are currently using.
Now that it’s easy to switch accounts, please come join the conversations in Google Plus. If you need an invitation, let me know in comments (use a Gmail address in your comment) and if you’re already there, please add me to your circles.



More and more, the web is adapting to who and where you are. Google tailors its search results when you are logged in and Facebook Connect allows websites to personalize your experience, based on your social graph.
