Key Passport is a MetaMask Snap that enables users to manage their identity, attestations, proofs, and cryptographic keys using their existing Ethereum account. It deterministically generates app-specific or ZK-proof credentials, stores them securely in MetaMask's sandboxed environment, and provides full control over keys and identities. This tool is ideal for Ethereum users seeking enhanced privacy and streamlined key management across multiple chains and applications.
