How to get sudo to prompt you for a password each time in linux

Open Terminal and type:
sudo visudo
Then scroll down to the line that reads:
Defaults        env_reset
And change it to:
Defaults        env_reset,timestamp_timeout=0
You can change 0 to any values (time in minutes). Setting it to 0 will ask for your password every time and -1 will make it never ask. The default is 15 according to man sudo 8, but some manuals say the default is 5. Have a look at the RootSudoTimeout wiki for more information.
Press CTRL + X to finish editing, Y to save changes, and ENTER to exit.
