You’re in a silent room. The exam clock is ticking. Suddenly, a red warning flashes: “Unauthorized device detected.” But you haven’t touched anything. Your phone is in your bag. Your laptop lid is closed. So what happened?
The problem is that Safe Exam Browser (SEB) doesn’t just watch your screen. It checks for other devices connected to your computer—and sometimes it sees things you didn’t even know were there. This checklist helps you understand exactly what SEB can detect about other devices, so you can prevent false flags before exam day.
Why This Checklist Matters
For students, a false detection can mean a failed exam or an academic integrity hearing. For proctors, understanding SEB’s limitations helps you avoid accusing innocent students. SEB is a secure browser that locks down the testing environment, but it has clear boundaries. Knowing those boundaries saves everyone time and stress.
Step 1: Understand What SEB Actually Scans
SEB does not scan your entire home network or listen for phones in the next room. It only detects devices that are directly connected to your computer via:
– USB cables (external drives, phones, tablets)
– Bluetooth (headphones, keyboards, smartwatches)
– Wi-Fi Direct (peer-to-peer file sharing)
– Internal hardware (secondary displays, built-in cameras)
It does not detect devices on the same Wi-Fi network unless those devices are actively sharing files to your computer. This is a common misconception.
Step 2: Check Your Secondary Displays and External Monitors
This is the most common culprit. SEB can detect if you have a second monitor connected, even if it’s turned off.
– Action: Disconnect all external monitors before starting the exam.
– Test: Go to your display settings (Windows: Settings > System > Display; macOS: System Settings > Displays). If you see more than one monitor listed, unplug it.
– Gotcha: Some laptops have a built-in display and an internal port for a secondary screen. If you’ve ever plugged in a second monitor, the system may still “remember” it. Restart your computer after disconnecting.
Step 3: Audit Your Bluetooth and Wi-Fi Connections
SEB can see which Bluetooth devices are paired and currently connected. A smartwatch on your wrist, a pair of wireless earbuds, or a Bluetooth keyboard can all appear as “other devices.”
– Action: Turn off Bluetooth entirely during the exam. Do not just disconnect devices—disable the radio.
– For Wi-Fi: SEB does not scan for other computers on the network, but it can detect if an external device is sharing files via Wi-Fi Direct (e.g., AirDrop on macOS).
– Test: Open your Bluetooth settings. If you see any device listed as “Connected” or “Paired,” disable Bluetooth.
Step 4: Test Virtual Machines and Emulators
Running a virtual machine (like VMware or VirtualBox) or an Android emulator (like BlueStacks) is a major red flag. SEB treats these as separate devices because they have their own virtual hardware.
– Action: Fully uninstall any VM software before the exam. Simply closing the window is not enough—the service still runs in the background.
– Test: Open your Task Manager (Windows) or Activity Monitor (macOS) and look for processes named “vmware,” “vbox,” “virtualbox,” or “bluestacks.” If you see them, you need to uninstall the software completely.
Step 5: Review Your Device Manager and Running Processes
SEB takes a snapshot of your hardware profile at startup. Any unusual device—like a USB microphone you forgot to unplug, a drawing tablet, or even a USB hub—can trigger a warning.
– Action: Unplug every USB device except your mouse (if required). Remove USB hubs, external drives, and charging cables to other devices.
– Test: Open Device Manager (Windows) or System Information (macOS). Scan for any device with a yellow warning triangle or anything labeled “Unknown device.” These are often the source of false flags.
Step 6: Run a Controlled Simulation Before the Real Exam
This is the most practical step. Many schools provide a practice exam environment that uses SEB. Use it.
– Action: Launch the practice exam with the exact same setup you plan to use on exam day.
– What to watch for: Does it flag anything? If yes, note what it says. Common messages include “External display detected” or “Unauthorized Bluetooth device.”
– Fix: Remove the flagged device, restart, and run the simulation again. Repeat until you pass the check cleanly.
Common Mistakes That Trigger False Positives
- Leaving a phone charging via USB: Even if the phone is locked, the USB connection makes it a “detected device.”
- Forgetting a wireless mouse dongle: Some mice use a USB receiver that SEB treats as an external storage device.
- Running background sync apps: Dropbox, Google Drive, or OneDrive can appear as file-sharing services. Close them completely.
- Using a laptop with a touchscreen: Rare, but some SEB versions flag touchscreen input as a separate device.
Mini Scenario: The Student with a Smartwatch on Silent
Maria was taking a proctored exam from home. Her smartwatch was on silent, sitting on her wrist. She had no notifications. But SEB detected it as a connected Bluetooth device and flagged her for “unauthorized communication.” The proctor saw the alert and assumed she was receiving answers. Maria had to spend 20 minutes during the exam explaining the situation.
The fix: Maria now removes her smartwatch entirely before any SEB exam and disables Bluetooth in her system settings.

FAQ
Q: Can Safe Exam Browser detect my phone if it’s on the same Wi-Fi network but not connected to my computer?
A: No. SEB only detects devices that are physically connected to your computer via USB or actively paired via Bluetooth. Being on the same Wi-Fi network is not enough for detection.
Q: What if I have a second monitor built into my laptop (like a dual-screen laptop)?
A: SEB can detect that as a secondary display. Some laptops allow you to disable the second screen in the display settings. Check your manufacturer’s instructions. If you cannot disable it, contact your proctor before the exam.
Q: Can SEB detect devices in the same room that aren’t connected to my computer?
A: No. SEB has no way to sense devices that are not connected to your computer via cable, Bluetooth, or direct network file sharing. It cannot see a tablet on your desk if it’s not plugged in or paired.
Q: Does SEB detect virtual machines like Parallels or VMware?
A: Yes. SEB treats virtual machines as separate devices because they have their own virtual hardware profile. You must uninstall the VM software entirely before the exam.
Q: Will SEB detect a USB hub even if nothing is plugged into it?
A: Yes. The hub itself is a detected device. Unplug it completely from your computer.
