Show HN: PanicLock – Close your MacBook lid disable TouchID –> password unlock

Great idea and implementation! If you are hesitant to install this for any reason, you can accomplish the same thing with this one liner:

  sudo bioutil -ws -u 0; sleep 1; sudo bioutil -ws -u 1

Edit: here's a shortcut to run the above and then lock your screen. You can give it a global keyboard shortcut in the Shortcuts app. https://www.icloud.com/shortcuts/9362945d839140dbbf987e5bce9...

Can you get TouchID to register multiple fingers and script the actions; maybe your middle finger unlocks touchID, but your index finger disables touchID until you enter your password.

The iOS equivalent is to hold the side + volume button until the power slider shows up. Cancel out of it and the next unlock will require your passcode. Pressing the side button 5x triggers Emergency SOS which does the same thing. Been there forever but barely anyone knows about it.

Nice to see something like this on the Mac side.

Neat idea.

I remember way back in the day, there was some question as to the legality of compelled unlocking of devices; IIRC, it’s been deemed legal to compel a fingerprint, but illegal (under the first amendment?) to compel entry of a password—IIRC, as long as that password hasn’t been written down anywhere.

I gather this is written to that end primarily? Or is there some other goal as well?

An opportune time to mention the real-world example of when the authorities really wanted to gain full access to a computer but did not want to resort to legal compulsion or "rubber-hose cryptanalysis" -- they simply waited until the target was logged in, staged an altercation in the immediate vicinity, and then snatched the open laptop away from them.

You can read about the sting, here: "How Did Investigators Catch the Dread Pirate Roberts (DPR) in San Francisco?" https://www.forensicscolleges.com/blog/forensics-casefile/si...

This is great. I see many times "security advice" against biometrics replacing password unlock, but most of the time I am more worried about getting recorded by somebody/something while typing a password in the open than anything else. This makes it better for those other cases.

Maybe clicking the Touch ID button could invalidate the login attempt and ask for password?

I like logging in with my finger print, but I would like an “out” in the same vein as this.

This would be perfect if it could monitor the force with which the lid is closed (macs have accelerometers after all, either this info or an acceptable proxy could be derived?).

Gently close? no action.

Stronger, faster action? Disable touch ID

Slam shut in full panic? yeah disable all biometrics, lose all state, even wipe the ram and the filevault key if it's an option
