# Configuring the QR code

The QR code is the most popular check-in method: visitors scan a code with their smartphone and reach the check-in kiosk. This guide shows you how to configure the QR code's advanced security options to protect your site.

**Audience:** Administrators, Managers
**Application:** Admin (app.anghello.co)
**Estimated time:** 5 minutes

## Before you start

- You need an **Administrator or Manager account** on Anghello
- The QR code is enabled by default on all sites

## Opening the security settings

**1.** In the left-hand menu, go to `Configuration` > `Sites`. On your site's card, click `Settings & features`.

**2.** Open the `QR Code - Devices` tab.

**3.** Click `Show advanced options` to expand the advanced options.

## The security options

| Option                        | Description                                                                                              | Default                   |
| ----------------------------- | -------------------------------------------------------------------------------------------------------- | ------------------------- |
| `Allow VPN connections`       | If enabled, visitors using a VPN on their smartphone can check in                                        | Disabled (VPNs blocked)   |
| `Allow proxy connections`     | If enabled, visitors coming through a proxy can check in                                                 | Disabled (proxies blocked) |
| `Filter by country`           | If enabled, only visitors whose connection comes from allowed countries can check in                    | Enabled                   |
| `ALTCHA verification`         | If enabled, visitors must solve a small verification challenge before checking in (anti-bot)            | Disabled                  |

**4. Save**

Click `Save` after making your changes.

> 💡 **Tip:** The default settings suit most organizations. Only change these options if your visitors run into trouble (for example, if your guest WiFi network uses a proxy).

## Enabling or disabling the QR code

You can disable QR code check-in if you'd rather use a tablet only.

**1.** In the site settings, on the QR Code - Devices tab, turn off the `Enable QR code check-in` option.

**2.** Click `Save`.

## Regenerating the QR code

If your QR code has been compromised or shared in an unwanted way:

**1.** In the advanced settings, click the red `Regenerate QR code` button.

**2.** Confirm in the security dialog.

|| **Important:** Regenerating **immediately** disables the old QR code. All previously printed posters and images will stop working. Remember to print a new poster.

## Good to know

> 💡 **Tip:** You can enable the QR code AND the tablet at the same time. The QR code for self-service visitors, the tablet for assisted reception — that's the most popular combination.

> 💡 **Tip:** The QR code's last regeneration date is shown next to the regeneration button.
