Here I've got a password protected web page.
http://www.jackson8.com/secret

Can any of you gurus get to it, or tell me how secure it really is?

Thanks!

If someone wants in they can do it. Since it's hosted on lunar pages, hackers would mainly try to hack the server directly, then get to the site through the file system.

One security suggestion, you could try to make the password box not appear over and over. This opens the site to a scripted dictionary attack. If possible, lock the user name/password until it is manually reset. If that is not possible, lock the account for a period like they do at askmehelpdesk.
