It's a very important feature that should be available in Clientexec. Many clients ask how they give cPanel permission to their developer. We suggested sharing the credential only. But, it's not a good way to deal as leaking credentials may have risks. The tech world is going to be passwordless by integrating third-party sign-up or login facilities such as using Google, Facebook, Twitter and so on. This one is also missing. But, it can be the easiest way to sign up for the new customer as human nature is much lazier to do extra staff. Besides, it's a more powerful way to manage the system.
