Centralized identity systems are prone to credential theft and phishing. Two distinct technologies are being developed to mitigate these issues: Self-Sovereign Identity (SSI) and Fast IDentity Online (FIDO). While SSI enhances security by decentralizing the storage of credentials, it introduces usability friction through wallet applications that users must install and manage. Conversely, FIDO offers easy password-less authentication but lacks SSI's fine-grained authorization capabilities. We combine the two technologies to present FIDO4VC: a novel, walletless, decentralized identity protocol that operates without requiring a wallet application on the user side. FIDO4VC leverages FIDO’s device-based key management to securely handle the SSI credential lifecycle. This creates an end-to-end solution offering the user sovereignty of SSI with the ease of use of FIDO. In this paper, we explain the architecture and its integration with OpenID protocols, demonstrating a secure and user-friendly decentralized identity paradigm.
