# Access Control: frequently asked questions about bookings and codes

Context: Access Control: administration, guest page and configuration in Link’nX

Short answers to common questions about Access Control: sign-in, site selection, bookings, access codes, guest emails, mobile display and hardware. Each answer points to the detailed guide.

## How do I sign in if I forgot my password?

Access Control administration uses a link received by email, without a password. On **Administration des accès** (Access administration), fill in **Votre adresse email** (Your email address), then select **Recevoir le lien de connexion** (Receive the login link). See the [sign-in guide](https://wiki.can-nx.com/en/guides/ac-login/).

## How do I choose my building, my site or my room?

In **Sites**, select the site in the list that appears under this menu. To book a room or a door, then choose **Nouvelle réservation** (New booking), then the access point under **Choix de l'accès** (Access point selection). See the [creation guide](https://wiki.can-nx.com/en/guides/ac-create/).

## Why does the booking planned for tomorrow not appear?

**Aujourd'hui** (Today) is not an exhaustive list: it shows active bookings and those starting within the next 12 hours. Open **Réservations → Toutes** (Bookings → All). See the [viewing guide](https://wiki.can-nx.com/en/guides/ac-consult/).

## Can I choose the code or change the door of a booking?

No. The code is generated on creation, and the access point cannot be changed when editing. See [Create a booking](https://wiki.can-nx.com/en/guides/ac-create/) and [Edit a booking](https://wiki.can-nx.com/en/guides/ac-change/).

## Why is the start date grayed out?

The booking has started: **Du** (From) can no longer be changed and the arrival can no longer be postponed. The editable fields are described in the [editing guide](https://wiki.can-nx.com/en/guides/ac-change/).

## How do I send the code to my guest?

Enter their address in the booking, then use **Envoyer** (Send) or **Renvoyer** (Resend). The email contains a link to view the code. If the guest has not received anything, follow the guide [Sending and delay](https://wiki.can-nx.com/en/guides/ac-notifications/).

## Is the sending delay specific to each site?

No. The **Délai d'envoi du mail d'accès (minutes)** (Access email sending delay, in minutes) field applies to your whole account. See [Set the delay](https://wiki.can-nx.com/en/guides/ac-notifications/).

## I am a guest: where are the Sites and Réservations menus?

The guest link shows your access and its period. The management menus belong to the administration. See [View your guest access code](https://wiki.can-nx.com/en/guides/ac-guest/).

## Where is the summary on mobile?

On a narrow screen, it may be below the fields of the booking form. Scroll down the page to **Récapitulatif** (Summary) before **Créer la réservation** (Create booking). If a menu remains inaccessible in your display, note the name of the screen; if the blockage persists, contact support.

## What if the code is displayed but the door does not open?

Check the access point and the period, then follow the [Access Control troubleshooting guide](https://wiki.can-nx.com/en/guides/ac-troubleshoot/). If these checks have already failed, contact the site administrator and support, without sending the code.

## Where do I declare the hardware or enter the administrator?

In Link’nX, the installer or an authorized administrator uses **Access Control** to [declare the hardware](https://wiki.can-nx.com/en/guides/link-accesscontrol-device/) and [enter the administrator email, then copy the Admin link](https://wiki.can-nx.com/en/guides/link-accesscontrol-admin/). Copying the link does not send an email. Bookings are then created in the Access Control administration.

## How do I import bookings, manage a license or change permissions?

These operations are not presented in the Access Control administration. Contact support to establish the steps to follow in your context.
