# Deploy Experience
FaceAR is a web-based library that enables you to view your 3D content through a web browser and supports face tracking.
## Adding 3D Content
Add **any type of asset** through the platform. You can choose **any type of target**. Here's how:
{% content-ref url="/pages/-M41wQICYWUWeloxCkls" %}
[Add Assets](/web-console/how-to-add-content.md)
{% endcontent-ref %}
## Launching the FaceAR App
### Option 1: Scan a QR code
Once the 3D asset is set you can view it instantly with FaceAR.
Click on the 
icon and then to show the QR codes. Choose the "See on a face" tab.
Scan the QR code with your phone's camera app or with a QR reader app.
{% hint style="info" %}
Latest iOS and Android phones are able to read QR code with their default camera apps.
{% endhint %}
Click the pop-up message to get redirected to our website. Your browser should open.
{% hint style="warning" %}
You might need to allow camera access. In iOS, we recommend using the Safari browser. In Android, Chrome browser is recommended as the default browser.
{% endhint %}
Your camera should open in the browser.
### Option 2: Go directly to website
Instead of scanning the QR code, you can also browse directly to:
```
https://api.echo3D.com/facear?key=
```
Your camera should open in the browser.
## Seeing 3D Content in AR
Now that the camera is running in your browser, keep the camera pointed to a face to see the 3D model appear.
## Capturing the AR Moment
You can snap a picture of the AR scene by clicking the 
button on the bottom of the screen.
An image will be captured and saved to your device.
**Share it with others!** 💗
## Password-Protecting Content
You can password-protect FaceAR experiences so that users that access the experience will be prompted to enter a password.
If you'd like to password-protect the 3D content, go back to the platform and [add metadata](/web-console/manage-pages/data-page/how-to-add-data.md#adding-metadata) to set a password. After adding metadata, [relaunch the experience](#launching-the-ar.js-app).
The following key is a word the system uses as pre-defined metadata keys to password-protect content:
| Keyword | Type | Example |
| ------- | ------ | ----------- |
| passwd | String | 1a2B3c4D5e6 |
