What is a fingerprint?
A fingerprint uniquely identifies the Plugin or Custom Client application assigned to that key. The fingerprint created is based on the bits of code making up your Plugin or Custom Client. Changing one line of code will result in a different fingerprint. Fingerprints are also tied to a key. Fingerprints are used with keys to provide two-factor authentication, allowing us to open our network to developers in a controlled manner. With this approach, we can make sure your key is used only by your code.
