Question about API tokens and User Question Libraries

Hi, I have a couple of quick questions about the API which I hope the community can help with;

  1. How do you invalidate an API token? Is a token invalidated when a user changes their password?
  2. Can you access a user’s question library via the API? (to add or remove questions programmatically for example)

Any and all help on this would be much appreciated, thanks all
