AES-256 PBKDF2 Argon2 Zero-Knowledge End-to-End Encrypted Open Source Audited

Security isn't a feature.
It's the architecture.

Cayo is built on a "Zero-Knowledge" architecture. This means your data is encrypted on your device using a key that you alone possess. We never receive your raw passwords, only unreadable encrypted blobs.

Encryption
AES-256-GCM

Military-grade standard. Impossible to brute-force with current technology.

Key Derivation
Argon2id

Protects your master password against rainbow table attacks.

Transmission
TLS 1.3

All data in transit is protected by the latest transport layer security.

Audit
Open Source

Our code is public. Anyone can verify our security implementation.

1. Local Encryption

Data is encrypted on your device using your Master Password.

2. Sync Encrypted Blob
