A WiFi QR code lets a guest join your network by pointing their camera at a sign — no spelling out a twenty-character password across a busy room. Enter the network name exactly as it is broadcast, add the password, choose the security type, and mark the network as hidden if it does not appear in the phone list. The credentials are encoded in your browser and never sent to us. Print the result for a café table, a hotel room card, an office reception desk or a holiday-let welcome folder.
