This guide covers how to sign in to the Crazyphone application for Mobile or Desktop.

# CrazyPBX - Linking the Crazyphone App

Crazytel offers the Crazyphone application for PC and Mobile - this guide covers how to sign in on both.

> This guide walks through the **CRAZYPBX EXTENSION** QR screen. Desktop sign-in works the same way for **SIP Trunks** and **Hybrid SIP Trunks**: open that product's QR screen and use the **Open setup link** under the QR.

## How does CrazyPBX work?

Crazytel allows multiple devices to register to a single CrazyPBX Extension. All devices must use the latest password for the CrazyPBX Extension.

When generating a QR Code for your CrazyPBX Extension, the Extension's password will be reset. This invalidates any devices signed in using the old password.

## Signing in to Crazyphone for Mobile

Signing in to the Crazyphone Mobile Application can be completed using a QR Code. The QR code should be used whenever possible as it eliminates the potential for typos/human error.

1. Sign in to the Crazytel Customer Portal and click **CrazyPBX**

2. Click **Extensions** on the left hand side to list all CrazyPBX Extensions you hold

3. On the Extension you want to sign in to, click the middle action button - "**Generate QR Code for Extension**"

4. You will be presented with a confirmation pop-up asking if you want to **Reset Password & Generate QR**

5. Click **Reset Password & Generate QR**. A QR Code will be displayed. Scan this QR code with the Crazyphone application for mobile.


## Signing in to the Crazyphone for Desktop

Signing in to the Crazyphone Desktop Application can be completed using a setup link. The setup link should be used whenever possible as it eliminates the potential for typos/human error.

1. Sign in to the Crazytel Customer Portal and click **CrazyPBX**

2. Click **Extensions** on the left hand side to list all CrazyPBX Extensions you hold

3. On the Extension you want to sign in to, click the middle action button - "**Generate QR Code for Extension**"

4. You will be presented with a confirmation pop-up asking if you want to **Reset Password & Generate QR**

5. Click **Reset Password & Generate QR**. A QR Code will be displayed -- underneath this QR code is a button titled **Open setup link**

6. If you are signing in to the Crazyphone app on your computer, launch the Crazyphone application, then click this button. A pop-up will show stating Crazytel is trying to open an external application. Click **Open Crazyphone** to sign in.

7. If you are resetting the password for someone else, right-click the **Open setup link** button and click **Copy Link Address**. Send this link to the person that needs to sign in.

## Signing in to both Crazyphone for Desktop and Crazyphone for Mobile

To sign in on both devices at the same time, complete steps 1-5 for either option. When the QR code is displayed, scan it with the mobile application, and click the open setup link to sign in on the desktop.
