Your school can send you a link that opens booking for one specific meeting event — no account, no sign-in. You click it and you are on the slot grid. The link is convenient, but it is not a sign-in and does not behave like one. This page describes where the boundary runs. The school issues the link and sends it in an invitation to a particular event. It is tied to two things at once: to you as a guardian, and to that one event. It is not an address you can type from memory — only the link you were sent works. For any one event you have one valid link. If you ask the school to send it again, the previous one stops working at that moment. So always click the one in the most recent message, and delete the older ones. This is the heart of the page. The link opens booking for only the one event it was issued for. The rest of the app stays closed. If you try to go anywhere beyond that one event, the app does not show you a blank page or somebody else’s data — it sends you to the normal sign-in. That is a deliberate boundary, not a fault.
The link does not create an account and does not replace one. If you want to do anything in Zebrania beyond booking this one event, create an account — Getting started covers passwordless sign-in, so there is still no password to invent.

​
How long it lasts

Two separate clocks run here, and they account for most of the surprises:
  • The link itself is valid for a limited time from when it was issued — 30 days by default. Within that window you can click it as often as you like; it is not used up on first click.
  • The session a click opens lasts 12 hours. After that your browser stops being recognised, even if the link itself is still valid.
The practical consequence: if you come back to booking the next day and the app does not know you, click the link in the message again. That is usually all it takes, and you do not need to ask anyone for a new one. The link also stops working once the school closes booking for that event. Validity is checked on every visit, so a closure takes effect immediately. The app names this case plainly. The heading is the same in both situations — “This booking link doesn’t work” — and the sentence below it differs: If you see the second message, copying is almost always the cause. Click the link inside the message rather than moving it to the address bar by hand. The link is the pass. The app does not check who clicked it — only whether the link is valid. Whoever holds it acts as you: they see your reservations for that event, can change and cancel them, and any slot they book is recorded under your name.
Do not forward this link — not to the class group chat, not to other parents. Passing on the link means passing on your access to booking.
There is one reason it works this way. Sometimes a grandparent who has no account is the one attending. You can then hand the link over deliberately, to that one person — fully aware that the reservation stays recorded under your name. If someone else is to book for your child regularly, a guardian invitation is the better answer: they get their own account and their own access, which can be withdrawn later.
