\# Configure Device Fingerprint \*\*Device Fingerprint\*\* is a security feature that helps improve fraud risk analysis in each transaction. Through the collection of non-sensitive information, it identifies the device used in a purchase and compares it with previous transactions to determine its security level. The Device Fingerprint configuration in VTEX stores must be performed through \[Google Tag Manager\](http://www.google.com/tagmanager), which allows inserting the necessary scripts. Follow the steps below to do it. > WARNING > > Each store must have only one active Device Fingerprint. Check if there is another connector that is already using it and, if so, remove it. 1\. Log in to Google Tag Manager with your username and password. If you don't have an account, you can create one by accessing the \[official site\](https://marketingplatform.google.com/intl/es/about/tag-manager/). 2\.
