Can I Log In from Multiple Devices?
Sign in from any device you like — a laptop, a desktop, a tablet, a phone — but only one session stays live at a time. Open the account somewhere new and the earlier session is closed for you, and the one that closes is told plainly why rather than just stopping.
This is not a cap on how many devices you may own or a list of machines you have to register. Every device works and you can move between them as you please. What is limited is the number of sessions running at once, and the limit is there to keep one login the work of one person.
One Active Session, Any Device
The account is not bound to a particular machine. Sign in on a laptop in the morning and on a phone at midday and each will let you in; what will not happen is the two being live together. When the newer sign-in succeeds, the older session ends, and it ends with a message saying someone has signed in under the same username — an explanation rather than a silent drop. Nothing on the account is lost; it is only that one browser session that closes. It behaves the way a device set to permit a single interactive login does, handing the line to the newest session rather than letting two contend for it.
Why a Single Session Keeps Your Practice Attributable
The rule earns its place on the record it protects. Your account holds the sittings you have finished, the scores they earned and the detail behind each attempt, and that history is only worth reading while it is one person’s. Were two people to share a login and sign in together, single-session enforcement is what stops their sittings overlapping: the newer sign-in keeps the account and the other session steps aside, told why. Your practice, and everything the account records about your networking certification exam preparation, stays yours to read.
Log in from as many devices as you like, one at a time: any laptop, desktop, tablet or phone will do, but a fresh sign-in always closes the last one, so your networking exam practice stays attributable to you.
