2. Click on "Account" ' link in the upper right corner and select "My Web Hosting".
3. On the Hosting Services page, where it says 'Update Hosting Password', simply enter a new password and confirm that password. Then enter your new password and confirm the new password. Be sure that the password is at least 8 characters long.
