Hi @Vincent-TP 

I believe you didnt get my point for this. Since i noticed it on my side, how about test it to your local side.

 

1. I created 10 vouchers for testing.
2. I used one voucher to connect Phone #1 to the network.
3. On Phone #1, I generated a WiFi QR code for the connected network.
4. I scanned the WiFi QR code using Phone #2 to connect to the same network.
5. Surprisingly, Phone #2 was granted internet access without entering a voucher manually.
6. When I checked the Authorized Clients section in the hotspot page, I noticed that Phone #2 was assigned a different unused voucher even though it was never manually entered in the voucher portal. The unused voucher becomes in-used status.

This suggests that the system randomly assigns an unused voucher when a device connects via a QR code, bypassing the intended voucher authentication process.

Could you please investigate this issue? It appears to be a concern as it allows devices to connect without manually redeeming a voucher.

Ive tested with two different android phones and it works. You can also connect using mobile hotspot.
1st has to enable hotspot and already connected to the wifi network using voucher code. 2nd phone will connect via wifi using the hotspot network created on the 1st phone.
