Secure Content

This may not be the best place for this but here goes:

My customer publishes a newsletter and would like to start offering it through her web site. The goal is that only subscriber would be able to access it. I know I could secure it using username and password but I guess there just might be 2 or 3 of the "subscribers" that may be tempted to share their uname and pwd. So basically I am looking for a really secure way of offering this newsletter.

Thanks for any ideas.
