Can I Log In from Multiple Devices?
The question really holds two, and they have opposite answers. How many devices may you use? As many as you like — DBExam is not tied to one registered machine, and any browser can open your Oracle certification practice. How many may be signed in at the same moment? Just one: only a single session is ever live on your account, so signing in somewhere new closes whichever one was already open. Free to move between devices, then, but one active login at a time.
Those two halves are easily blurred, so take each on its own — first the device side, which is open, then the session side, which is the one real limit.
Any Device with a Browser, No App to Install
You reach DBExam the same way everywhere: through an ordinary web browser, with nothing to download and no native app on any platform. There is no list of approved devices to register and no per-machine limit, so a desktop, a laptop or a tablet all reach the same account, and you move between them as freely as your day requires. Whether a small screen is a comfortable place to sit a full Oracle exam is its own question, and the answer sits on the Can I Use DBExam on Mobile or Tablet? page; here the point is only that the browser, not an installed app, is the door on every device.
Why Only One Oracle Session Stays Live
The limit is on sessions running at once, not on the machines behind them. Your account holds one live session and gives it to your most recent sign-in: begin a new one and the earlier session simply stops being active, so two are never answering under your name together. Sign in on a second machine and the first session ends; come back to the first later and it just asks you to sign in again, with nothing lost in between. That is the concurrency side of the rule; the same single session also does security work, alongside the password on your account, which Is My Data Secure on DBExam? takes up.
So yes, move across as many devices as you like — the account travels with you rather than living on one machine — provided you accept that only the newest sign-in stays live and each fresh one closes the last. A browser on each device is the whole requirement, there is no app to install, and the single-session rule caps how many logins run at once, never the devices you use for your Oracle practice.
