I have a user with a blank password, but now I can't run sudo with that account.
sudo ls
Password:
Sorry, try again.
Password:
Sorry, try again.
Password:
sudo: 3 incorrect password attempts
Is there any way around this?

1Is there a particular reason you can't change the password to do this and then change it back?– Steve ChambersDec 27, 2020 at 16:56

Genius! Can’t ssh into a computer if the password is NULL either afaik. Same with emoji in the password, if you can’t type it, you can’t use it to authenticate.– bmike ♦Dec 28, 2020 at 16:43

sudo on macOS requires the account to have a password:
https://support.apple.com/en-us/HT202035
Therefore it is not possible to just press ENTER to continue at the prompt, like you would expect from some other systems.
This behaviour is enforced through a configuration of the PAM subsystem. You can change the settings for that in /etc/pam.d, where you have a sudo file that setups the authentication requirements for the sudo command.
WARNING: Changing the contents of the files in /etc/pam.d incorrectly can deny you from logging to your system at all. Only make changes if you know what you're doing, you have a backup - and you feel confident in booting in Recovery mode to undo your changes if it should fail.
