How to remotely log out from Google chrome?

Very easy, you must go to Security settings, then you just change your password and this will log all computers out of anything to do with your Google chrome account and it also stops that computer logging back in if the password was saved on that computer, until you get back to that computer station again.

To remotely log out of Chrome's browser sync, you can revoke access to Google Chrome in your account permissions settings. This will prevent someone else from using that browser to delete your bookmarks, for example, but it won't clear bookmarks, cookies, or saved passwords from that browser. (Unfortunately, it doesn't seem like any of the other options here guarantee that either.)

Might be very old but there is a new way to do that

You can check all your recently connected devices and you can also remove devices here.

Note, that this would log you out of all your Chrome browsers in all PCs, and you may loose your syncing data.

Go to Google Accounts dashboard. Scroll down to Chrome sync and then click on Stop sync and delete data from Google.
