Keyhive: Local-first access control
Keyhive is a project exploring local-first access control. It aims to provide a firm basis for secure collaboration, similar to the guarantees of private chat but for any local-first application.

OAuth API - Home
The Apigee OAuth API gives you a keychain for authenticating to Twitter, Salesforce, Salesforce Chatter, Facebook, Flickr, and Foursquare. Thousands of developers complain about the complexity of using OAuth. Now you can easily authenticate in one consistent way across several APIs and build apps faster.
AChep/keyguard-app
A password manager that supports Bitwarden platform and KeePass (KDBX) files. It autofills your logins, supports passkeys, works offline, and runs a Watchtower that finds leaked and reused passwords and other issues.
Passkeys.directory
A community-driven index of websites, apps, and services that offer signing in with passkeys.

Decentralized Identity Verification using Zero-Knowledge Proofs: A Privacy-Preserving Authentication Framework
In the contemporary online interaction, digital iden- tity is central, but most systems follow a centralized provider like Google or Facebook. Although convenient, these models pose ma- jor risks to data breach, surveillance, and single point of failure. The proposed paper proposes a privacy-sensitive decentralized identity verification system that uses Zero-Knowledge Proofs (ZKPs) to allow users to make it through claims (e.g., age, citizen- ship, or enrollment) without any personal data being provided, thereby solving the challenges outlined in the paper. Our architecture integrates verifiable credentials, zero-knowledge-SNARKs and an issuer trust registry that is maintained on blockchain smart contracts to guarantee trustless verification and eliminate dependence on centralized authorities. Its system gives its users full control over credentials, allows reuse across applications, and does not expose data.A proof-of-concept implementation has shown the approach to be feasible with Circom and SnarkJS to generate proof, Solidity smart contracts to verify them, and a user interface implemented in React. Results of the evaluations showed that determination of the verification latency is low, the overhead to generate proofs is moderate, and no privacy leakage occurs. It can be used in potential applications such as education, e-governance, healthcare, finance, and online voting.
