Create Two Login Pages on Website

I have a website that the server does not support php so the solution couldn't be php. I need to have two seperate login pages created that a user would have to type in a password to access the two secured areas on the website. There would be only one password for each login section so there is no need for anyone to create an account, just one universal password required. In one of the login sections I currently have two php forms that would need to be converted so they would run properly in the new environment. The forms are already set up. I would then populate the secured areas with html files. Thank you for your bids! Tara
