Google Inc. is a multinational public cloud computing, Internet search, and advertising technologies corporation. Google hosts and develops a number of Internet-based services and products, and generates profit primarily from advertising through its AdWords program.
Recently Google has officially announced support for Multiple Sign-In which allows users to be signed in with three accounts at the same time.
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.
Google notes that there still are some restrictions:
1) Not all Google services support multiple account sign-in yet. For the services that don’t support it (like Blogger and Picasa Web Albums), you’ll be defaulted to the first account you signed in with during that browser session.
2) We’re still working on making Gmail and Calendar work offline with multiple sign-in. If you rely on offline access, you probably don’t want to enable this feature quite yet.
3) Multiple account sign-in only works on desktop browsers for now, so if you use Gmail on your phone’s browser you won’t see this option yet.
