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?
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:
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.
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.
