If you have access to your account’s cPanel control panel, you can change your email mailbox password by logging into cPanel and clicking the Mail > Email Accounts icon, then clicking the Change Password link next to your email address.

If you don’t have access to cPanel, the recommended way to change your password is through Webmail (a cPanel function). Here’s how. Open a browser window and go to http://www.yourdomain/webmail/, where “yourdomain” is you domain name. Log in to your mailbox with your full email address and mailbox password. You’ll be presented with a landing page like this, and the Change Password link is to the lower left.
