Being the only one who has current access is only part of the equation.
There is more to risk than just malicious actor access. And this includes- user mistakes.
Here is a guide that can enable you to access Root Terminal by default:
Pointlessly, you can also alternatively set up a Root Terminal keyboard shortcut that you can tap instead of ctrl+alt+t to pull up a Root Term. You still would have to enter your password (once) in order to launch it.
And it is just as easy to launch terminal with ctrl+alt+t and run
and enter your password one time and get pretty much the same effect.
Lastly, I use a 4 digit PIN as my root password. It makes it a lot faster and easier to enter my password a lot. I really use no other tricks than that... it is effective enough.
