# Access from a link, without signing in

> Opening bookings from an event link.

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.

## Where the link comes from

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.

## What the link can and cannot do

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.

|                                                                  | With an event link | Signed in to an account |
| ---------------------------------------------------------------- | ------------------ | ----------------------- |
| See free slots for this event                                    | ✅                  | ✅                       |
| Book, change and cancel a slot at this event                     | ✅                  | ✅                       |
| Open a different event — even at the same school                 | ❌                  | ✅                       |
| See your list of children and their details                      | ❌                  | ✅                       |
| Sign a consent, enrol a child in a class, change contact details | ❌                  | ✅                       |
| See notifications and your calendar                              | ❌                  | ✅                       |

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.

<Note>
  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](/en/getting-started) covers passwordless
  sign-in, so there is still no password to invent.
</Note>

## 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 link stopped working

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:

| Message                                                                                      | What happened                                                                                                                                    | What to do                                                                                     |
| -------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------- |
| "The link may have expired or been revoked. Ask the school to resend your event invitation." | The link lapsed, was replaced by a newer one, was revoked by the school, or booking for the event has closed. The app does not tell these apart. | Check whether you have a more recent message. If not, ask the school to resend the invitation. |
| "This booking link is incomplete. Open the full link from your invitation email."            | The link was truncated — usually by copying and pasting, or by a mail client.                                                                    | Go back to the message and click the link directly instead of retyping it.                     |

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.

## Why you must not forward the link

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.

<Warning>
  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.
</Warning>

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](/en/invitations#guardian-invitation) is
the better answer: they get their own account and their own access, which
can be withdrawn later.
