You can change your email passwords through the webmail interface.  Just login to webmail and look for the "change password" link at the bottom.  To get to the webmail interface, open http://yourdomain.com/webmail in your browser.  Put in your actual domain name where it says yourdomain.com.

You can change your cPanel and FTP  password in the cPanel interface.  Administrators can also change email passwords in the cPanel interface.  The link is in the top section called "preferences".

To change your management account password, login at https://linux25.com/clientarea and change it there, or if you don't know your password, click the link that says "Request a password reset" on the login page.

To change your cPanel password, login to cPanel at http://yourdomain.com/cpanel and use the change password link, or request a password reset through our support system in the management interface.
