Log in and out with Master Key to view and hide protected photos

On my test site https://t.kristinn.no I have tested protected photos. including logging in and logging out.

this worked well. Now I’m thinking of putting this on the page https://myvo.is where I mix together private and non-private pictures.

I don’t find out how I can set up the Home page so that I can enter the Master Access Key. to see the hidden ones.

I entered this on the test page which gave me the option to turn off and on the display of protected images
Protect photos
now I can open for displaying protekted on the test page but it does not close for viewing
page Albert - Kristinn testweb Contains only protected images

How do I set up myvo.no so that the login message appears and how do I put the protection back on?
