For those who uses Nix/NixOS, I made a flake just to slightly simplify @Shy_Guy’s solution with 2 lines of command:
$ sudo nix develop "github:nixvital/fprint-clear"
# After entering the environment
$ fprint-clear
You can find the code in GitHub - nixvital/fprint-clear: Quick solution to clear your fprint storage flake.nix.
