Page Locker group password

Hi

I'm trying to use Page Locker to password protect some pages set up using the Articles package. I want to protect the top resource (article holder) and all resources it contains (the articles) with the same password so you can move freely between the articles and article holder having entered the password once. I have set up password and password group TVs.

I want to set this single password for the password group. Where do I put this password. If I have to put it on every page, it makes it very time-consuming to change the password!

Thanks for any help anyone can offer.
