how can I set up password-protected Guest account

This question was asked 2 years ago and still hasn't been answered.

If there is not a way to add a password to guest account, what is the script that get's executed when the Guest account log's off? I can execute that on an account that I create called 'localGuest' or something like that.

I have an enterprising member of my family who has figured out that my computer is exempt from the network curfew and they are using Guest to bypass that. I have since disabled guest; however, I do like using the fresh guest environment to test software development.

Does the answer here help?

I am fairly sure I could accomplish something like that with my own bash script; however, It is obvious that they [said scripts] already exist for the guest account. I was hoping someone know the location of those and the method(s) used.

I do not know, but often you'll find Apple doings like that are Hard Coded.
