Whin i submit this form, the username and password is visible in firebug…
How do i hide my password ?
This is my login.php
[code]
Sign in [/code]You should use SSL (HTTPS) when handling sensitive data. Note that this also includes the cookies (like the session cookie) after a user is authenticated. Using SSL you can rest assured the data is transferred encrypted from the client to the server 
There are addional measures that could be taken if you want a zero-knowledge system (system never sees the username/password), but that is probably not applicable here.
Thanks, But How???
Setting up SSL depends on your hosting situation. I would suggest contacting them
After you have it working (can access your site through https) you can just either force all users to always use https, or you can only do it for login + logged in users.
Thanks
