Security Architecture
Password
Argon2id
Master Key
Secured
Your password undergoes memory-hard Argon2id hashing to derive a 256-bit master key locally.
Zero-Knowledge Proof
Keys are derived entirely in your browser. Our servers receive only the salt for future login -- never your password or master key. This means:
Client-side derivation
Argon2id runs in your browser, not on our servers
Zero-knowledge architecture
We store encrypted blobs; we cannot decrypt them
No backdoors
Even with a court order, we cannot produce your plaintext
All cryptographic operations run locally in your browser
