CPanel connection on WordPress | Talk Web Hosting

Hello,
I'm trying to give my users the ability to connect with their cPanel account on my WordPress site to access the store and account settings without having two accounts.
A button "Connection with cPanel" would be enough. What would be even better than that is that they just tap their login data from cpanel and access their account.

Thanks in advance
