Is there any way to make sudo forget my password instantly instead of remembering it for 5 minutes?

Edit your sudoers file by running visudo as root.

Look for the Defaults line, and add timestamp_timeout=0 to the end.

Eg.

Defaults env_reset,timestamp_timeout=0

If you just want to make sudo ask again for the current session

sudo -k
