Abstract

Password managers make it easy for users to choose stronger and more random passwords without the burden of memorizing them. While the majority of our passwords should be kept secret, sharing passwords and access codes is necessary in some cases. In this paper, we present GPASS—a password manager architecture that allows groups to share passwords via an untrusted server. GPASS provides its own cryptographic access control mechanism in which all the information is transparent to the clients so that they can detect any misbehavior of the server. We implemented a proof-of-concept prototype to demonstrate the feasibility and effectiveness of the architecture.
