Need help setting up a password on mywebsite, Password help Options

[Emanuel]

Hello:

I am in the process of making a website. I have no problems making the website except I don't know how to add a password on my site.

My ISP don't allow me to telnet on his site so I can't create an .htpasswd file so that mean I can't use the .htaccess file.

I need to create a password where the users can delete his or her password or change the password if he or she wish to.

Is there a cgi script I can use or a software I can use to create the password.

This is what I need on the site.

Customer can signup and make account
Customer can then login to his or here account and change their information
Customer can delete his or her information
Customer can change his or her password.

I need to start working on the website but I need to get that important part fixed up first.

Thanks in advance
