Reset cPanel Password
To reset your cPanel password, you should first log in to your client area at https://archhosting.net/clientarea.php
Then, you should visit the "Services -> My Services" option on your navigation bar.
Next, click the Web Hosting order for the account you wish to reset the password for.
Then, click the "Change Password" option on the left sidebar.
You should then enter, and confirm, your new password. This will update your cPanel account password.
To find your cPanel username, you should check the e-mail you were sent upon signup titled "Your website has been set up!". If you can't find the e-mail, click the "Hello yourname!" button on the top right of your client area and click "Email History" to view the email contents.
