Could you build this?
Partial A secure password manager demands rigorous, audited cryptographic implementations (like zero-knowledge key derivation and CRDT-based encrypted sync) where subtle vibe-coded bugs can lead to total security failure.
What it would actually take: Building a reliable local-first password vault requires cryptographic engineering: PBKDF2/Argon2id for master key derivation, AES-GCM or XChaCha20-Poly1305 for envelope encryption, and a decentralized sync protocol (like WebRTC or peer-to-peer WebSockets with end-to-end encryption and CRDT conflict resolution). It requires security architecture expertise and independent audits to guarantee zero-knowledge guarantees.
