The USEB Companion Browser is a premium feature bundled with our 1-Year and Lifetime plans. It's a lightweight Electron-based application that runs alongside UnSafeExamBrowser and gives you a separate, controllable workspace during an exam session.
USEB ("UnSafeExamBrowser Companion") is a standalone browser application included inside the same installer as UnSafeExamBrowser when you purchase a 1-Year or Lifetime license. There is no separate download or setup — it's already there when you finish installing.
Once UnSafeExamBrowser is running, USEB sits in the background, ready to be shown or hidden at any time. Common use cases include:
USEB is controlled with a single global keyboard shortcut:
Shift + A + S
Press and hold Shift, then A, then S. The first press shows USEB; the next press hides it. There is no delay, no animation, and no notification — the switch is instant.
The Companion Browser is most useful when you need a second surface that you can summon and dismiss quickly. Because it runs as a separate process, it doesn't interfere with whatever is happening inside UnSafeExamBrowser itself.
You don't need to install anything extra. You don't need to download a separate executable. You don't need to configure ports or settings. If your plan includes USEB, the toggle just works.
