# Access Control: guest bookings and access codes

Access Control is the administration of guest access: a booking gives a guest an access code for a specific access point, for example a door or a room, during a defined period. The guest views this code from a personal link received by email. The documentation covers sign-in, booking management, sending the guest link and troubleshooting, for both the administrator and the guest. The interface is in French; labels are given in French with their English meaning.

## Getting started

- **Prepare the access points.** Before any booking, the installer or an authorized administrator declares each access point in Link’nX, with Zenio, Blumotix BX-E-AK12 or DoorBird Cloud hardware, then saves the **Administrator Email**: see [declare an access control device](https://wiki.can-nx.com/en/guides/link-accesscontrol-device/) and [enter the administrator](https://wiki.can-nx.com/en/guides/link-accesscontrol-admin/).
- **Sign in.** The administration does not ask for a password: enter your address in **Votre adresse email** (Your email address), then open the link you receive. See [signing in with an email link](https://wiki.can-nx.com/en/guides/ac-login/).
- **Find your way.** The navigation offers **Aujourd'hui** (Today), **Sites**, **Réservations** (Bookings) and **Paramètres** (Settings). **Aujourd'hui** only shows active bookings and those starting within 12 hours. Check the site name at the top of the page before acting: see [view bookings](https://wiki.can-nx.com/en/guides/ac-consult/).

## Main tasks

### Bookings

- [Create a booking](https://wiki.can-nx.com/en/guides/ac-create/) from the site page: access point, optional guest address, **Du** (From) and **Au** (To) period, time zone. The code is generated on creation; you do not choose it.
- [Find a booking](https://wiki.can-nx.com/en/guides/ac-consult/) in **Réservations**, with the **Toutes** (All), **En cours** (Current) and **Terminées** (Ended) filters, then show its code.
- [Edit, extend or delete a booking](https://wiki.can-nx.com/en/guides/ac-change/) that is active or upcoming. The booked access point cannot be changed, and **Du** can only be edited before the start.

### Guest link and code

- [Send or resend the guest link](https://wiki.can-nx.com/en/guides/ac-notifications/) from the booking row. The automatic email leaves before the access starts, according to a delay of 1 to 10080 minutes set in **Paramètres** for the whole account.
- [Show your access code](https://wiki.can-nx.com/en/guides/ac-guest/): the guest opens their personal link, without signing in, and uses the code on site during the authorized period.

## Troubleshooting

- The [Access Control troubleshooting guide](https://wiki.can-nx.com/en/guides/ac-troubleshoot/) covers a missing booking, a refused creation or edit, an email not received, an unavailable code and the DoorBird Cloud programming indications.
- The [frequently asked questions](https://wiki.can-nx.com/en/guides/ac-faq/) cover a forgotten password, choosing the code, the sending delay per site and the mobile display.
- Only an on-site opening test, during the period, confirms that a code works. Never send a code or a personal link to support.
