Can I Log In from Multiple Devices?
You can sign in from any device — a desktop at work, a laptop at home, a tablet on the move — but your account runs one live session at a time. Log in somewhere new while a session is already open, and the earlier one is signed out; the newest sign-in becomes the only active session, and the device it displaced is told that someone has signed in to the account.
This is not a restriction on which devices you own or a cap on how many you may register. Every device is welcome; what the account holds to is a single sign-in being live at once. Switching machines simply means the latest login takes over and the previous one steps aside — no setting to change, no device to pre-approve.
How EduSum Keeps One Live IT Exam Session
Handing the live session to the newest sign-in is an account-integrity feature, and it reads cleanly against a security exam topic: a stale or stolen session is dangerous mainly for how long it stays valid. If a session token were left alive on a borrowed or public machine, anyone returning to that screen could pick up where you left off. Because a fresh sign-in retires the previous session, a stale one cannot stay open in parallel — the moment you sign in again, any earlier session on another device is closed out. One live session is easier to reason about, and safer, than several running unseen.
Not a Device Limit on Your IT Exam Account
It is worth being clear about what this is not. It is not account sharing — the single live session is precisely what stops one login being passed around several people at once, since the moment the next person signs in the last is dropped. And it is not a registered-device scheme that ties your account to particular hardware; you are free to move between as many devices as you like, one sitting at a time. If reading comfort across those devices is the real question, Can I Use EduSum on Mobile or Tablet? covers which screen suits a timed run best.
So yes, log in from as many devices as you want — just one at a time. The newest sign-in holds the live session and the previous one is dropped, an account-integrity measure that keeps a single IT exam session live rather than a limit on the devices you use.
