About this app

PC Bio Unlock allows you to unlock your PC using your phone's biometric scanner.
Supports Windows and Linux.

Get the desktop application: https://meis-apps.com/pcbu
Check out our GitHub: https://github.com/MeisApps

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

Linux features:
- Unlock sudo
- Unlock polkit (pkexec)
- Support for GNOME, GDM, KDE, SDDM, LightDM and Cinnamon

Pairing methods:
- Wi-Fi
- Bluetooth (requires Wi-Fi for initial pairing)

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

Security:
During the pairing process, a random key is generated to encrypt all traffic between your devices.
This key is not accessible to normal users. Your credentials are encrypted and stored on your PC.

Additional notes:
To pair, both devices must be on the same network or Wi-Fi. The pairing server uses port 43295 by default. If you are using a custom firewall, you may need to add a rule for this port.
The pairing 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.

I had problems before getting this to work, I came back to try it every now and then and now it seems like everything is now working seamlessly. Whatever issue with Windows not detecting my password seems to be fixed! The app is perfect for my use case now and is great for another layer of security wherever you can avoid entering your password.
