QR Code Format
A Unifi WireGuard QR code is a two-dimensional barcode that encodes information necessary to establish a secure WireGuard connection. It contains the following data:
Public Key
The public key of the WireGuard server.
IP Address
The IP address of the WireGuard server.
Port Number
The port number on which the WireGuard server is listening.
Preshared Key
An optional preshared key used for authentication.
Scanning and Importing
To scan a Unifi WireGuard QR code using a mobile device, open the camera app and point it at the QR code. Your device should automatically recognize the QR code and prompt you to import the WireGuard configuration.
Once you tap on the prompt, the WireGuard configuration will be imported into your device’s WireGuard app. You can then connect to the WireGuard VPN by tapping on the “Connect” button.
Importing the WireGuard Configuration
If your device does not automatically recognize the QR code, you can manually import the WireGuard configuration by following these steps:
- Open the WireGuard app on your device.
- Tap on the “+” button in the top right corner.
- Select “Import from QR code.”
- Scan the QR code using the camera on your device.
- Tap on the “Import” button.
Once you have imported the WireGuard configuration, you can connect to the WireGuard VPN by tapping on the “Connect” button.
Troubleshooting
Unifi WireGuard QR code implementation can encounter various issues. This section provides guidance on identifying and resolving common troubleshooting scenarios.
Understanding the potential challenges and solutions will ensure a smooth and efficient setup process.
Identifying Common Issues
- QR code scanning issues
- Device compatibility problems
- Network connectivity errors
QR Code Scanning Issues
QR code scanning issues can arise due to several factors. Ensure the QR code is clear and not damaged, and that the scanning device has a stable internet connection. If the QR code is still not recognized, try refreshing the code or generating a new one.
Device Compatibility Problems
Not all devices are compatible with Unifi WireGuard QR codes. Check the device’s specifications to confirm compatibility. If the device is incompatible, consider using an alternative method to configure WireGuard.
Network Connectivity Errors
Network connectivity errors can prevent the QR code from being processed. Ensure that the device is connected to a stable Wi-Fi or cellular network. If the network connection is unstable, the QR code may not be able to be processed successfully.
Security Considerations
While Unifi WireGuard QR codes offer convenience, they also introduce potential security risks. Understanding these risks and implementing best practices is crucial to protect your network.
QR Code Interception
QR codes can be intercepted by malicious actors during transmission or when displayed publicly. Intercepted QR codes can be used to gain unauthorized access to your network.
Best Practices for Secure QR Code Handling
- Transmit QR codes securely using encrypted channels.
- Display QR codes in private and secure environments.
- Avoid sharing QR codes with untrusted individuals.
- Disable QR code functionality when not in use.
- Regularly monitor your network for suspicious activity.
Advanced Configuration
Customize Unifi WireGuard QR codes with advanced settings to tailor them to your specific requirements.
Access the Advanced Settings section to configure advanced options such as:
Customizing Interface Settings

- Set the MTU (Maximum Transmission Unit) for the interface.
Configuring Peer Settings
- Define the public key of the peer you want to connect to.
- Specify the allowed IP addresses for the peer.
- Configure the endpoint address and port for the peer.
Advanced Security Settings
- Enable or disable encryption for the WireGuard connection.
- Configure the encryption algorithm and key size.
- Set the keepalive interval and timeout values.
