Frequently Asked Questions
Why is my Wi-Fi QR code not working?▼
Verify that the SSID and password are correct. For hidden networks, check the "Hidden Network" option. Some older devices may not support WPA3 encryption.
Can I change the QR code colors?▼
Yes, but ensure sufficient contrast between colors. Dark foreground with light background works best. Light foreground colors may reduce scan reliability.
Where is my generated QR code stored?▼
