Web applications dealing with personal data in a privacyfriendly way have the need for anonymous credential systems. While there are already protocols describing anonymous credential systems and libraries, implementing the protocols, application using the libraries are rare. Without applications supporting anonymous credentials, companies will not start building a credential infrastructure and vice versa. This paper presents an easy way to issue and use anonymous credentials for web applications. By reducing the initial cost for both parties, the barrier of “starting first” can be lowered.
