Proctorio Secure Companion App
Overview
Proctorio uses a free application alongside the Proctorio Secure Exam Proctor Extension to provide enhanced exam security when Advanced Security settings are enabled. The required application depends on your device:
- Windows and macOS: Proctorio Desktop (Companion) App
- Chromebook: Proctorio Mobile App
Both the extension and the applicable app must be installed when Advanced Security is required. If needed, Proctorio will prompt you to install or launch the app during the pre-checks before your exam begins.
The Desktop App conforms to Proctorio's Privacy Policy and does not collect or transmit personal data, access your personal files or folders, or permanently modify system settings.
Download the App
You can install the required app before exam day using the links below. If the app is not installed when you start your exam, Proctorio will guide you through the installation process.
App store installation is recommended because it supports automatic updates.
| Platform | App Store (Recommended) | Direct Download |
|---|---|---|
| Windows | Microsoft Store | Windows Download |
| macOS | Apple App Store | Mac Download |
| Chromebook | Google Play Store | Not available |
Launching the App
When Advanced Security is required, Proctorio displays an Advanced Security pre-check to confirm that the appropriate app is installed and ready. The steps vary depending on your device.
Windows and macOS
- On the Advanced Security pre-check page, select Launch to open the Desktop App or Open Store to install it.
- Once the app is connected, return to the pre-check page and select Run Now.
- If prompted, close any listed applications or background processes to continue.

How it works:
- Windows: The Desktop App closes unauthorized applications before your exam. You may be asked to close applications or background processes manually.
- macOS: The Desktop App uses Apple's Assessment Mode to restrict access to other applications during your exam. Some applications, such as screen-capture software, may still need to be closed manually.
Chromebooks
On compatible Chromebooks, Advanced Security is provided through the Proctorio Mobile App instead of the Desktop App.
- Open your exam in the Chrome browser with the Proctorio extension installed.
- On the Advanced Security pre-check page, select Launch to open the Mobile App or Open Store to install it.
- The Mobile App opens automatically. If prompted, sign in to your learning management system or assessment platform again within the app.
- Complete the remaining pre-checks within the Mobile App to begin your exam.

During the assessment, the Mobile App restricts access to other applications and device functions.
