Hey Product Hunt! 👋 Maker here. I’m Erik, and I built Zero-Knowledge Vault to solve one thing: most “secure” vaults still require trusting the provider. What makes this different: 1) True zero-knowledge Encryption happens client-side. We only store encrypted bytes and cannot decrypt your data. 2) Passwordless passkeys WebAuthn login with Touch ID / Face ID / Windows Hello / security keys. No passwords to steal, phishing-resistant by design. 3) Security-first stack Rust backend, XChaCha20-Poly1305 encryption, Argon2id hashing, PostgreSQL + audit logs. 4) Built for real-world teams Useful for legal, healthcare, finance, and engineering teams that need strong privacy and compliance support. What you can do today: - Store encrypted notes, passwords, and files - Login with passkeys - Import from Google Drive / OneDrive - Use free tier (5GB), Pro (100GB), Enterprise (1TB) Try it: https://emvproject-production.up... GitHub: https://github.com/EJ-blip2026/e... I’d love feedback from this community: If you were evaluating a zero-knowledge vault, what’s the one feature or concern you’d check first?
