With the popularity of Google, millions of people use various services daily. With bunch of services from Google one person may have different user name and password for various Google services like Gmail, Docs, Codes, Sites etc and therefore it is painful to remember and key-in multiple credentials at the same time. Now Google is working on a feature which will allow all of its users to sign-in to any Google service in the same browser.
Many times you want to login to different Google service with different credentials while you have Gmail already opened in your browser. At that scenario other Google service will try to allow access using the same credentials supplied to, already opened, Gmail. This way it makes user experience little creepy. Now given a thought towards its huge user base of various services Google is all set to launch single browser log in feature in next couple of days or week so.
At first look, feature look great. But there is no draw back. If you carry away this feature, you wont be able to access your Gmail account in offline mode.
