# Obfuscating Data
The obfuscation mode of the [widget](/docs/integration/widget/) helps you protect sensitive information from bots. A common use case is to obfuscate email addresses on websites, preventing automated scraping bots from collecting them.
## Use Cases
- **Hide Email Addresses and Phone Numbers**: Protect email addresses and phone numbers on websites to prevent automated scraping bots from collecting this information.
- **Mask Personal Identifiers**: Hide personal identifiers such as usernames, IDs, or account numbers that could be used for malicious purposes.
- **Obfuscate Download Links**: Hide direct download links for files or software to prevent scraping.
## Configuration
After integrating the [widget](/docs/integration/widget/) and enabling the obfuscation plugin, configure the `data-obfuscated` string in the widget. Note that the obfuscation mode __does not use__ `challenge`:
```html
Send us an email, and we'll be in touch soon.
Email:
```
Any elements inside the `` tag will be displayed as placeholders for obfuscated data. The widget automatically detects clickable elements, such as `button` and `a` tags, which trigger the verification and de-obfuscation process when clicked.
## Demo
The code above will render something similar to this demo:
Send us an email, and we'll be in touch soon.
Email:
Click the _Click to reveal_ link to display the actual email address.
The widget can mask any textual data, here is a demo with an obfuscated address:
Our Address:
## Generating Obfuscated Data
To generate obfuscated data, use the `npx` command:
```sh
npx altcha-lib obfuscate "mailto:hello@example.com"
```
This command outputs base64 encoded data that can be directly used in the `obfuscated` attribute.
