Abstract

Section titled “Abstract”

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, wallet-less, 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.

How this site relates to the paper

Section titled “How this site relates to the paper”

The paper is the authoritative research treatment, formatted for an academic audience. This site is a re-authored version with overlapping content but a different framing:

  • The paper emphasizes the academic contribution (combining SSI + FIDO; novel proof-of-concept; related-work positioning)
  • This site emphasizes the implementer’s view (normative cryptosuite spec, integration guide, runnable repositories)
  • The site adds product-facing use cases (long-lived credentials, AI agent delegation) beyond the paper’s four academic use cases
  • The site includes spec-grade detail on the cryptosuite that the paper only describes conceptually

If you’re evaluating FIDO4VC for adoption, this site is the better entry point. If you’re reviewing the research contribution or citing FIDO4VC, the paper is the citable artifact.
