# What is Face ID?

After generating a request, you will receive a face ID, which serves as a unique identifier for your face. 

This token allows you to use all subsequent API requests related to your face, such as modifying, understanding, and generating stickers.

{% hint style="info" %}
Face ID is generated based on the photo and style. For every new photo and new style, the Face ID will be different.
{% endhint %}
