For security reason, login to your cpanel account, go to email, beside your email address, clcik on configure device
One of the most important thing to remember:
Alway use a hard coded password, not something anyone can find, you can use the tools inside your cpanel - mail to generate a strong password.
We log our different servers, and each day there are tons of attempts from countries such, China, Vietnam, Russia, Turkey, Netherlands, France and others trying to brute force the accounts.
Fortunately, we have strong security in place and all attempts are blocked right at the root.
But still, use a strong password and sleep well.
*** cpanel account have SSL secure certificate already integrated.
