What is Zero-Knowledge Architecture?
Zero-Knowledge Architecture is a security design principle that ensures the service provider (us) cannot access or view any user data, even if the data is stored on our servers.
KeyMe Pass's Zero-Knowledge Promise
We promise you:
- ✅ We can never access your master password (PIN)
- ✅ We can never decrypt your stored data
- ✅ Even with sync enabled, we can never view any plaintext
- ✅ Your data is completely under your control
Technical Implementation
1. Encryption Completed Locally on Device
All data is encrypted before it leaves your device. This means:
- The encryption key (DEK) is only stored on your device
- The server can only see encrypted data
- Even if we wanted to view it, we couldn't decrypt it
2. Key Derivation is Irreversible
Your PIN is used to derive the encryption key through a Key Derivation Function (KDF):
- We cannot reverse-engineer your PIN from the encryption key
- Even if we obtained the encryption key, we couldn't know the original PIN
- This is a one-way function, mathematically irreversible
3. Server Only Acts as Storage
Our servers are only responsible for:
- Storing encrypted data
- Providing data transmission services
- Not participating in any encryption/decryption process
Why Does This Matter?
Zero-knowledge architecture protects you from multiple threats:
- Server Attacks: Even if attackers gain access to server data, they cannot decrypt it
- Insider Access: Our employees cannot view your data
- Legal Requests: Even if law enforcement requires it, we cannot provide plaintext data
- Data Breaches: Even if a data breach occurs, your data remains encrypted
Your Privacy, Your Control
At KeyMe Pass, we believe:
Your data belongs to you, and only you should be able to access it. We simply provide a secure storage and sync service, but we should never, and can never, see your data.
Conclusion
Zero-knowledge architecture is not a marketing slogan, but a core design principle of KeyMe Pass. We ensure through technical means that we can never access your data—this is our highest commitment to your privacy.
