# Verification code not working?

When connecting a **secondary device** (mobile phone or tablet) to your assessment session, Talview uses a verification code to securely pair the secondary device with your primary device (laptop or desktop). This process ensures both devices are correctly linked for proctoring.

If the **verification code is not working**, fails to validate, or does not connect your device, review the troubleshooting guidance below.

***

### ✅ Common causes and fixes

| **What might be wrong** | **How to fix it** |
| :- | :- |
| Incorrect verification code entered | Ensure all **8 digits** are entered exactly as shown on the secondary device. Re-enter the code carefully. |
| Network connection is unstable | An unstable or switching network can interrupt verification. Ensure both devices are on a stable internet connection. Avoid switching between Wi-Fi and mobile data during pairing. |
| Page refreshed or navigated away during verification | Refreshing or leaving the page mid-process can break the connection. Keep both devices on the verification screen until the pairing is confirmed. |
| Unsupported or in-app browser used on secondary device | In-app browsers (for example, links opened inside Gmail, WhatsApp, or SMS apps) may block verification. Open the QR link in a supported browser such as **Chrome (Android)** or **Safari (iOS)**. |
| Secondary device screen locked or app minimized | Keep the secondary device screen ON and the browser open until the device is connected. |

> [!TIP]
>
> **Additional Tips:**
>
> * Close background apps on the secondary device before scanning the QR code
> * Scan the QR code again and enter the newly generated 8-digit code immediately
> * Ensure both devices remain powered and connected to the internet throughout the process
