# yubikeylockd

Simple daemon for locking and unlocking macOS with Yubikey.

## Install

Via Homebrew formula:

```

brew tap shtirlic/yubikeylockd https://github.com/shtirlic/yubikeylockd

brew install shtirlic/yubikeylockd/yubikeylockd

```

## Additional requirements

  * [YubiKey using the native smart card (PIV) mode](https://www.yubico.com/why-yubico/for-businesses/computer-login/mac-os-login/)

  * Require password *immediately* after sleep or screen saver begins

## How it works

When you attach Yubikey for the first time `launchctl` will run `yubikeylockd` daemon

that will simply monitor the state of the Yubikey USB devices.

Daemon based on the sample provided by Apple for IOKit development.

It does two things:

* when device is attached it makes activity via

```IOPMAssertionDeclareUserActivity``` call to turn screen on

* after device is detached it uses ```IORequestIdle``` to put display to sleep and (if you configured it) also locks the OS X
