FIDO
Another core Janssen Project component, this server provides the enrollment and authentication endpoints which enable people to use USB, Bluetooth, or platform FIDO credentials.
An example of a USB FIDO credential is a Yubikey. An example of a platform FIDO credential is Apple TouchID. These powerful new credentials not only are more secure than passwords, and they are also phishing resistant.
