Zero-Knowledge Proof is a method for one party (the prover) to prove to another party (the verifier) that a statement of the prover is true without telling the verifier that statement.

This concept is expanded to Zero-Knowledge Encryption, which helps users authenticate their identity to a server or store encrypted data on it without providing any of their passwords or security keys. Thus, only users can access their data.

Locker cannot know or retrieve users’ passwords and any other confidential data. All data is secured with end-to-end encryption using each user’s email and Master Password. Locker does not store and cannot access any user’s Master Password or security keys.
