How to Enable and Use Google Multiple Sign-in Feature?

Google has introduced a new feature called “Multiple Sign-in” which allows you to sign into multiple Google accounts simultaneously from same browser so now you no longer need to sign out from one Google account to use another Google account.

Following are the how to instructions taken from the official announcement:

1. Open Google Accounts page and look for a new option “Multiple sign-in“. If you don’t see the new feature, it will probably be enabled soon.

2. Click on “Edit” link or use this link to directly edit “Multiple Sign-in” settings.

3. After clicking on the link, Google informs that this is an advanced feature and that it will only work for Gmail, Google Calendar, Google Sites, Google Reader, Google Voice, App Engine and Google Code.

Click on the “On” option and select all available checkboxes and then click on “Save” button.

When you enable this feature, you’ll see a new drop-down next to your email address in Gmail and other supported Google products. Click on the drop-down and you can sign in to a new Google Account without signing out from the previous account.

NOTE: If you use multiple sign-in, the first account you sign in to will be your default account. If you visit other Google products that don’t support multiple accounts after you’ve signed in, you will automatically sign in to your default account for that product. If you sign out of any Google product while signed in to any account, you will be signed out of all your Google Accounts at once.
