The sample web application provides a web interface where you can have an in-depth look at the FIDO UAF ceremonies including request response structures from the FIDO Server perspective. It is based on the Spring Framework, which uses the OneSpan FIDO UAF SDK with the UAF 1.1 API to perform FIDO actions such as registration, authentication, deregistration, and transaction confirmation.
In addition, the FIDO sample web application exposes the FIDO UAF server functionality via a REST API, which can be integrated with a UAF mobile client.
