Penetration test and code review of the 1Password system

Data is encrypted with AES-GCM-256. The vault key is derived from your account password using PBKDF2-HMAC-SHA256 at 650,000 iterations, then combined with a 128-bit Secret Key that never leaves your devices — so an attacker who guesses the password alone still cannot decrypt anything. Authentication uses SRP, so password-equivalent data is never sent to the server.

The vault is encrypted client-side with AES-256 in CBC mode plus HMAC-SHA256 — an encrypt-then-MAC construction, so tampering with the ciphertext is detectable. The key is derived from the master password with Argon2d (3 iterations, 32 MB memory, 2 threads); PBKDF2 remains only as a backward-compatibility fallback that Dashlane says it will deprecate in 2026. All vault fields are encrypted, including usernames, item URLs and notes — not just passwords. Support for legacy CBC-only mode was removed in November 2025.
