If you have multiple GMail accounts (for regular GMail or Google Apps), you might have experienced signing in and out or using different browsers to check your accounts. Google’s multiple sign-in solves this problem as it lets users login and use 10 Google accounts, including their products/services, open simultaneously in a single browser.
Here’s how you enable Multiple sign-in:
2. Under the Personal Settings area, you’ll see that your Multiple sign-in status is off. Click “Edit”.
4. Sign out for the changes to take effect then sign back in.
To sign in to your other Google account:
2. Click the “Sign in to another account” link to sign in to your other Google account which you’ll be adding.
3. After signing in to the other account, it will be added on the list of Google accounts that you’ll be switching to.
Here are the products that support the multiple sign-in feature:
Alerts, Calendar, Code, Docs (Google Apps accounts only), Finance, Gmail, Google+, Google Moderator, Groups, iGoogle, Maps, News, Profiles, Reader, Sites, Voice, Web Search.
