Users/Password Protect Sites

Howdy Folks,

I was wondering if anybody had know-how or feedback about how to go about the following.

Need to create a site that has users (simple), those users have an option to purchase a auto-generated password that gives them access to the video that they purchased on a page within the site. Been looking around at different plugins, and blog articles, but just wanted to see if anybody had any other insite or suggestions.

The clients main concern is they don’t want passwords to be passed around like wildfire so I’m thinking that the user and password for the video all have to match in order to gain access.

Thanks
Simon
