# Mask with AutoDetect

This method automatically identifies and masks personal/sensitive data within specific text.

* The ProtectoVault object is instantiated with your tokenization key.
* The input should consist of a list of values to be masked.
* The `mask` method is used to automatically identify and mask personal/sensitive data within the provided text.

***Note:*** \
To obtain the `<auth token>`,please refer to the [Step-by-Step Guide to Obtain Your Auth Token](/tokenization-packages/protecto-tokenization/step-by-step-guide-to-obtain-your-auth-token.md).

*Code Snippet*&#x20;

```python

# Import the ProtectoVault class from the protecto_ai module
from protecto_ai import ProtectoVault
# Create an instance of ProtectoVault with your authentication token
obj = ProtectoVault("<auth_token>")
# Pass a list of sensitive information as input for the mask method
result = obj.mask(["George Washington is happy", "Mark lives in the U.S.A"])
# Print the masked result
print(result)
```

*Result*
