Encrypted Raspberry PI-2 Kali setup requires manual entry of password

I used the following article:

To create an encrypted Kali PI-2 image, it works fine except that it manually requires me to enter the encryption password each time it boots.

What did I do wrong and where should I look to fix this issue?

Thanks!

That's expected behaviour.

Not much point having an encrypted computer that automatically takes anyone straight to the desktop.
