Unauthorize apps from Google

Question

I'm trying to un-authorize one of the apps that I've allowed previously to use my Google information.

Twitter and Facebook allows un-authorization. How do you achieve it in Google? Tried looking around the settings, but to no avail.

Answer 1

https://www.google.com/accounts/b/0/IssuedAuthSubTokens is the URL to view/revoke permissions granted to third-party apps.
