Supports Windows and Linux.

Windows features:
- Unlock the Windows logon/lock screen
- Unlock UAC prompts

Linux features:
- Unlock the login/lock screen (GNOME, GDM, KDE, SDDM, LightDM, Cinnamon, Hyprlock)
- Unlock sudo and polkit (pkexec)
- Unlock SSH logins for configured hosts

Connection methods:
- Wi-Fi
- Bluetooth (requires Wi-Fi for initial pairing)
- Cloud (unlock from anywhere over the internet, subscription required)

There is a Pro version with additional features:
- Direct unlocking (shows the biometric prompt immediately)
- Auto unlock (when the phone is in Wi-Fi or Bluetooth range)
- Wearable notification (allows unlocking from a watch)
- Unlimited devices
- Ad-free

There is also a Cloud subscription. It includes everything in Pro, plus unlock from anywhere. Traffic is end-to-end encrypted.

Security:
Your PC password never leaves your PC. It is stored encrypted on the computer; the phone holds the key and never sees the password.
Traffic between your devices is encrypted with a key created during pairing. Cloud traffic is end-to-end encrypted, so the servers cannot read it.

Additional notes:
To pair locally, both devices must be on the same network or Wi-Fi.
The unlock process can be cancelled at any time by pressing Ctrl+Alt on the PC.
Wake on LAN is also supported and a widget is available.
There's a Wear OS companion app for Wake on LAN too, and it comes with a tile so you can wake your devices without having to reach for your phone.
