One of Google's Chrome's features is the ability to sign in with your Google account and sync your history, bookmarks, apps, and extensions across multiple PCs.
Signing in also helps improve your Google Now suggestions, and automatically signs you in to Google services like Gmail, Drive, and Google .
The downside: If you share a PC at home, other family members can start searching the web as you by simply opening Chrome.
Also if you manage multiple gmail accounts for your business or customers.
Luckily, Chrome’s multiple profile support can help, providing an easy-peasy way for multiple people or gmail accounts to use the same browser without worrying about having to constantly sign in and out of all your different Google profiles.
I have made a video showing you how to do this. Once set in place it will speed up your work progress tremendously.
