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.

Each record is encrypted client-side with its own 256-bit AES-GCM key; those record keys are wrapped by a per-user Data Key, which is in turn wrapped by a key derived from the master password with PBKDF2-HMAC-SHA256 at 1,000,000 iterations (128-bit salt) — the highest iteration count among the managers reviewed here. Every field is encrypted, including URLs, titles, notes, custom fields, TOTP secrets and file attachments. The offline cache uses a separate randomly generated Client Key protected with PBKDF2-HMAC-SHA512. A hybrid Kyber key-encapsulation layer began rolling out across the clients in November 2025.

The product is run by Dashlane, Inc.; the brand and trademarks belong to Dashlane SAS, France. The company is independent and venture-backed — it has raised over $200M across five rounds, the last a $110M Series D led by Sequoia Capital in May 2019, with Bessemer Venture Partners, FirstMark Capital and Rho as earlier backers. It has not been acquired. Dual headquarters in New York and Paris.

Founder-led (Darren Guccione, CEO; Craig Lurey, CTO), headquartered in Chicago with a product office in El Dorado Hills, California and sales offices in Cork, Ireland and Tokyo. Two minority growth-equity investments: Insight Partners ($60M, August 2020 — the company's first outside equity) and Summit Partners (May 2023). No majority-stake acquisition; the founders retain control.
