A blank passcode keypad: the numbers and letters on the Lock Screen passcode buttons are hidden, so only the circles show.
The buttons, the passcode dots, Emergency and Cancel work exactly as before.
Pressing a button doesn't reveal its number either.
Only the Lock Screen keypad changes: other number pads (Phone, Settings) are untouched.
No settings. Install, respring, done. To turn it off, uninstall it.
Device Support
arm64 and arm64e (A12 and newer) builds, made with Xcode's toolchain and checked for the correct arm64e format.
Tested on an iPhone 7 (A10) with iOS 15.8.6 and Dopamine. iOS 16 and A12 and newer aren't confirmed yet: please report back. If it puts you into safe mode, open Sileo (safe mode still allows it) and uninstall it.
Notes
Make sure you know your passcode by heart: the keypad layout is the standard one (1 2 3 / 4 5 6 / 7 8 9 / 0).
Only for rootless jailbreaks with ElleKit (Dopamine).
