What Is Zero-Knowledge Encryption?
Zero-knowledge encryption (also called zero-knowledge proof architecture) means the service provider encrypts your data in a way that even they cannot access or decrypt it. Only you hold the encryption key (your master password), so the provider has 'zero knowledge' of your stored data.
Also known as: zero-knowledge proof, zero-knowledge architecture, end-to-end encryption
Why Does Zero-Knowledge Encryption Matter?
With zero-knowledge encryption, even if a password manager's servers are breached, your passwords remain encrypted and unreadable. This is the gold standard for password manager security — if a provider doesn't use it, your data could be exposed in a breach.
