I hope this article will help you those, they are using multiple Google account. I was wondering when I use my second Google account because I have to logout from the current session and login to second one or vice verse Recently I just came across an article which describes about "Sign in to Multiple Google Accounts in the same browser". This is not a new feature but many of us are still unaware of this. So I thought to share this with my readers.
Google provides a feature, which allows you to sign in more than one account using the same browser session at a time. This feature does not support all of their products. The products which we can use this feature are desktop versions of Alerts, Calendar, Code, Docs (Google Apps accounts only), Finance, Gmail, Google+, Google Moderator, Groups, iGoogle, Maps, News, Profiles, Reader, Sites, Voice, Web Search, YouTube. Other Google products and the mobile versions of the above products do not support the use of multiple accounts
If you use multiple sign-in, the first account you use to sign in during that browser session will be your default account for the rest of that session. 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. You can sign in to ten accounts at a time.
To enable multiple sign-in:
1. Go to the multiple sign-in settings page.
2. Sign in to your account.
3. Click Edit beside the option “Multiple sign-in”.
3. Select the option "On - Use multiple Google Accounts in the same web browser" and select the checkboxes to confirm that you understand how to use multiple sign-in. Read more about what you need to understand before using multiple sign-in.
4. Click Save changes.
When multiple sign-in is turned on, you can click the arrow next to your address (at top right) to switch between accounts
