How to type a blank password in terminal in Mac sierra I use Sudo commands  in terminal but it always asks for the password.This is annoying because I always have to set a password.So how do I type blank password in terminal in MacOS Sierra 10.12.5
sudo in macOS requires a password, see https://support.apple.com/en-us/HT202035
So it is not about typing it, it is sudo not accepting it.
