The vault is protected by a symmetric document key, itself wrapped by a root key derived from your vault password via PBKDF2-HMAC-SHA512 at 210,000 iterations. Cure53's March 2026 audit flagged this as GPU-crackable and recommended a memory-hard function (Argon2id or scrypt) instead.

The vault is encrypted client-side with XChaCha20-Poly1305-IETF at 256 bits. The master key is derived from the master password with Argon2id and a 16-byte salt (iteration count not published). Zero-knowledge — NordPass says it only verifies that you hold the key, without ever storing it.
