PC Bio Unlock - Troubleshooting

Failed to connect to the PC

This error can be caused by many different reasons due to various different network configurations. Here are some things you can try:

• If you haven't already, please check your Firewall on your PC or router. As configuring the firewall varies between software and the router model, you might need to look up online how to do this for your setup. The app automatically detects Windows Defender, ufw and firewalld and adds a rule for them. The default port is 43295 and can be changed in the desktop app's settings.
• The desktop app tries to automatically detect the IP address of your PC, so your phone can connect directly to it. However, on some setups this detection might fail so manually setting the IP is required. Go into the desktop app's settings and select a different network interface. Then save and try again.

Can't log in to Windows/Microsoft account during pairing

Microsoft account: Please use your Microsoft account password. Passwordless accounts are not supported due to API limitations.

Local Windows account: Please use the normal account password. Do not use your Windows Hello PIN if you have that set up.

I can't login / I'm locked out of my account

If you are stuck at the login screen and can't log in with PC Bio Unlock you can abort the process anytime by pressing Ctrl + Alt. In rare cases a system update might break PC Bio Unlock functionality, making you unable to log in. If this occurs you can temporarily remove the unlock module from your system like so:

Windows: Go to C:\Windows\System32 and delete win-pcbiounlock.dll. You can also use a cmd as administrator and run del C:\Windows\System32\win-pcbiounlock.dll

Linux: Open the terminal and run rm /lib/security/pam_pcbiounlock.so

Note: On repeated failed login attempts, Windows and Linux automatically lock your user account for a specific amount of time, for example, 10 minutes. In that case, you need to wait until your account is unlocked again.
