Can't disable safe sleep

[Philflow]

I'd like to disable safe sleep so I use "sudo pmset -a hibernatemode 0"

It asks me for my password. I didn't set any password so I just give enter.

It says incorrect password.

Any ideas?

Straight from Apple
"If your administrator account has no password (a blank password), you must give that user a password before using the sudo command."
