Customize Lock Screen to show Sleep button or allow BTT shortcuts to work in Lock Screen Use case: I am logged in, at one point I locked the machine, and the Lock Screen is being displayed, prompting for a password.

MacOS catalina - 10.15.3


I am looking for a way to Sleep the machine without having to put the password to unlock. Via shortcut while in the Lock Screen, or via adding a button/menu item in the Lock Screen.


I couldn't find any way to customize the lock screen in MacOS. 


I tried setting up shortcuts with Better touch tool - the shortcuts (e.g. Ctrl+Cmd+Options+) work fine while the machine is unlocked, but do not work in the lock screen.
I also tried setting up trackpad shortcuts which don’t work on lock screen
Finally I also tried creating a MacOS "normal" shortcut (Preferences > Keyboard > Shortcut > All Apps, menu item = "Sleep"), which also works fine while logged in + unlocked but does not work in the lock screen


Why I want this: I setup the machine to not sleep while AC power is ON, this is my preferred setting while in the office. On occasion, say at the end of the day, I still want the machine to enter sleep mode. Often, I find the machine in Lock Screen mode.
Limitations of macOS

macOS's Lock Screen is not customisable.

Third Party Tools

Third party tools, such as Power Manager, can be used to customise your Mac's energy saving settings and schedule.
