What is Device Fingerprint?

Device fingerprinting is a process used to identify a device or browser by determining which technology, such as the Operating System (OS) and browser plugins along with other active settings, are present. Unlike website cookies that are stored on a user’s device, device fingerprints are stored server-side.

Device fingerprinting is used to track users and determine if they are unique or a known visitor. This method gives webmasters an important insight into who is visiting their site but comes at the cost of user privacy.
