We begin to login at the Portal Home. This is the Login Page for the Client Area of WHMCS. It contains a line for the email address and a password. They are different than the login details for your cPanel.
Enter your email address. Then enter your WHMCS Password. Now click on Login. That's all. You are now logged in to WHMCS and can begin to manage your hosting services, invoices, billing information, and more.
When you are done, click on the Logout Link in the upper right corner. You are now logged out of the account. There is a Click here to Continue link. Click that link. This will take you to the Portal Home.
This is the end of the tutorial. You now know how to login to WHMCS.
