sudo with no password

If you’re the only user on your system, you don’t need to be prompted every time you run the sudo command.

Add yourself to the sudoers file.

# create a new file
sudo visudo -f /etc/sudoers.d/users

Add this line.

# add your username
username ALL=(ALL) NOPASSWD:ALL

Exit and try again.

# exit out and login again
exit
# try to sudo again
sudo -i
# there's no password prompt for sudo this time
