HTTP Authentication -- How Secure?

Hey, I use HTTP Authentication on my website through a php script. I am wondering how secure/insecure that is?

I have heard it isn't that hard if you know what you are doing to get passed it.

This true?

You can check out how I use it at mc0.cjb.net and go to admin.

Thanks for all help and advice provided.

 

Hello,

Your are using .htaccess
I presume you crypted your pwds with htpw.exe ?

Here some good explanations :
