Zero-knowledge

Encryption and decryption happen entirely on your device. Keypsafe servers store only ciphertext — even a full database breach doesn't reveal your secrets.

Two recovery factors

Every vault is protected by a passkey and a password + recovery key. Either factor alone can decrypt. Losing one is never fatal.

Open cryptography

AES-256-GCM, Argon2id, HKDF-SHA256. Published security model and threat model. No proprietary crypto, no trust us claims. Open source after audit.
