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.
Military-grade standard. Impossible to brute-force with current technology.
Protects your master password against rainbow table attacks.
All data in transit is protected by the latest transport layer security.
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

3. Secure Sharing
Keys are exchanged securely to allow family access without leaks.
Built for real life.
