Chrome - Open separate browser windows, each in incognito mode, that do not share data between [duplicate]

I would like to be logged into 3 different gmail accounts at once.

I thought that command/switch combination would accomplish this by opening new browser windows with separate incognito mode:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -incognito --new-window https://mail.google.com

Clicking on the shortcut will launch a new window, and it will be incognito, and it will be directed to gmail. I then log in, and then rerun the shortcut and log in with my next account

But, the 2nd window that launches is logged in as my 1st user (why is chrome sharing cookies accross incognito windows - scary!) If I change the log in inside session 2, I then lose the 1st session's log in!

I need the igcognito windows to each be in their own session. How can I acheive this?

Any ideas?

Thanks

(Note: I actually want to acheive this with an intranet site - not gmail, but I am using gmail to illustrate my point)

Solution 1:

All incognito windows share a common set of cookies - this is by design.

Your best option is to use an extension such as MultiLogin.

Solution 2:

You can start several instances of Chrome with different profiles, each having an isolated set of cookies.

Also, google supports being logged into several accounts at once to some extent, but this does not really apply to your case.
