Zero-Knowledge Password Manager
Vault encrypted in the browser, synced as ciphertext, with autofill
5-6 weeks build
Overview
The master password never leaves the device: Argon2id stretches it into a key, and every vault entry is sealed with AES-GCM in the browser before it is synced. The server stores only ciphertext and a separate login verifier, so a database leak reveals nothing readable. A browser extension decrypts locally and autofills login forms on matching domains.
What makes it stand up
- 01Argon2id key derivation with tunable memory and iteration cost
- 02Per-entry AES-GCM encryption through the WebCrypto API
- 03Server holds ciphertext only, with a separate login verifier
- 04Multi-device sync with version numbers and conflict resolution
- 05Browser extension that autofills only on an exact domain match
Module breakdown
- 01
Key derivation
Splits the Argon2id output into an encryption key and a login verifier.
- 02
Vault crypto
Encrypts, decrypts and re-keys entries entirely client-side.
- 03
Sync API
Stores versioned encrypted blobs and resolves concurrent edits.
- 04
Extension
Detects login forms, matches the domain and fills credentials.
- 05
