Multiple Profiles in Chrome all Synced with one Google Account
Solution 1:
chrome://settings/
Under "People," pick "Add Person."
To use the same gmail account for this "person," tick the option to "Control and view the websites this person visits from ."
You will now see a button with the current Person's name. Pick on it and you can switch to a different one.
The only caveat here is that the bookmarks etc. will not sync. So, if you use more than one device on a regular basis, this may not solve your issue.
Solution 2:
Base on this Google Product Forum answer to the question: "Can Chrome sync 2 Different PROFILES using 1 GMAIL account?", it is not possible to use the same google account to sync more than one profile on different devices.
You would have to use external syncing tools to work around that problem, such as xbrowsersync.org.
