Logged into the root account in GUI on Kali Linux

Set Kali root password and enable root login

Until recently, Kali Linux used the root account by default and now you need to set Kali root password manually. In the latest versions of Kali, root login is disabled, forcing you to login to the GUI as your normal user account. The reasoning behind this change should be obvious, but if you’re a Kali user, you probably know your way around a Linux system by now, and there’s not much risk in letting you use the root account to login.
