# 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. <br />Re-enter the code carefully.                                                                                        |
| Network connection is unstable                         | An unstable or switching network can interrupt verification. <br />Ensure both devices are on a stable internet connection. <br />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. <br />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. <br />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
