We have had Greasemonkey scripts for Firefox and extensions on Chrome which allow people to sign in and jump from one Google account to another with a simple click of a button.
Google has been working on multiple sign in and I think it is being made widely available with many Google accounts.
How to enable Multiple Google accounts?
- Just head over your Google accounts manager and then click on it to enable multiple sign in with Google.
- This way once you log in you will see options as seen in the image below when ever your sign into your Google account for Google Calendar, Google Docs
- This is great because from a security point of view its better than any external browser extension.
- If this option is not available to you now, do not worry it should be there within the next couple of days.
