If I open two incognito windows (Ctrl+Shift+N) and sign in service in one of them, I singed in other (the same cookie, I guess). How to do independent this two windows?

Incognito Mode Windows are limited to one per Chrome profile. To get more than one (without installing another instance of Chrome), you could add a new Chrome profile. More details here.

  • Can I run profiles simultaneously? – Suncatcher Apr 8 '20 at 7:47
  • @Suncatcher - yes, you can open up many Chrome profiles and each one would have its own Incognito Mode window. support.google.com/chrome/answer/2364824 – miketreacy Apr 8 '20 at 13:29
  • Last time I switched between profiles they were replacing each other in current Chrome window, maybe things have changed since then. Will try again. – Suncatcher Apr 8 '20 at 13:51

Option 1: Use another, independant running instance of chrome, eg: http://portableapps.com/apps/internet/google_chrome_portable

Option 2: Setup another user profile and limit how long cookies etc are stored: enter image description here

  • How independent? That link appears only to be good for Microsoft Windows users. Is it good enough to run chrome again from a terminal, say? Or perhaps on GNU/Linux I could use cgroups to make sure the chromium server application can't communicate to the other incognito session's browser tab processes? – lmat - Reinstate Monica Apr 30 '18 at 13:23

    It's very cumbersome to create new profile each time you gonna create new incognito session. No other way? No automated way? – Suncatcher Feb 2 '20 at 18:39

What you are looking for is SessionBox (link). It is the analogous of Multi-Account Containers for Firefox.

Each Box/Container stores cookies separately, so you can log into the same site with different accounts and online trackers can’t easily connect the browsing, i.e. for every browser window or tab you can log in to the same site with a different account.

You can customize tab's labels and colors to help keep your different activities or accounts separate.

  • that one is awesome! – igor Feb 7 '19 at 14:59
  • though not really an incognito window – igor Feb 7 '19 at 15:00
  • is it really important? – sound wave Feb 7 '19 at 18:22
  • if you consider not leaving traces in browser history it can be important yes – igor Feb 8 '19 at 19:18
  • This is for the moment my best alternative. Very good extension, even a bit difficult to manage in the beginning. – рüффп Feb 4 at 10:57

--temp-profile

On Ubuntu 18.04 Chromium 80, using temporary profiles instead of incognito windows worked:

nohup chromium-browser --temp-profile > /dev/null 2>&1
nohup chromium-browser --temp-profile > /dev/null 2>&1

If I login on Stack Overflow in the first instance, I still need to login into the second one.

As far as I can see, no data carries over from my main Chromium session into those, for example passwords are not remembered by the browser either.

Interestingly, also giving the --incognito option with --temp-profile appears to disable the --temp-profile, and logins are shared, which is unexpected.

  • Does this work on Windows? I tried "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --temp-profile C:\Windows\Temp and it opened another Chrome window with mine profile, maybe I'm doing smth wrong? – Suncatcher Apr 8 '20 at 7:54
  • @Suncatcher I don't know about Windows, let me know if you find something else. You don't need to pass C:\Windows\Temp . – Ciro Santilli新疆棉花TRUMP BAN BAD Apr 8 '20 at 8:18
  • On my side I also tried this using Ubuntu WSL + Chrome.exe but temp-profile's seems also to be shared (not working). On Windows + Chrome, I went with the SessionBox extension which is working fine. – рüффп Feb 4 at 10:55
