[Update]

I closed the notebook and reopen it after 1.5h, now running drive.mount() will require a new key. Not sure the minimum amount of time needed to wait... not sure if that is normal to wait...

I mounted to Google drive account A. Now I want to switch to account B but I cannot do that, because there is no way for me to enter a new authentication key when executing drive.mount().

What I have tried and failed:

  1. restart browser, restart computer
  2. use force_remount=True in drive.mount(), it will only automatically remount account A. Not asking me for new mounting target.
  3. change account A password
  4. change run-time type from GPU to None and back to GPU
  5. open everything in incognito mode
  6. sign out all google accounts

Is there any API that can:

  • forget previous authentication key so it will ask me for a new one?
  • dismount drive and forget previous authentication key?

You can reset your Colab backend by selecting the 'Reset all runtimes...' item from the Runtime menu.

Be aware, however, that this will discard your current backend.
