You can log in to your cPanel account directly from your Listedhosting account dashboard. Thus, you don’t need to remember your cPanel login details. Login to your listedhosting account and click on services, then select the particular service you want to check its cPanel then on the right-hand dashboard you will find a link to login directly to your cPanel.
If you would like to log in through the cPanel login page instead of the Listedhosting dashboard, but receive an error about invalid login details, recheck the cPanel credentials that were sent to Your Hosting Account Email, then try logging in again (make sure there are no extra spaces).
