Bitwarden is an open-source password manager that enables individuals, teams, and enterprises to securely store and manage credentials with zero-knowledge encryption—meaning Bitwarden cannot access user data. The platform serves over 10 million users across 180+ countries and offers specialized products including a Password Manager, Secrets Manager for developers, and Passwordless.dev for building FIDO2 WebAuthn authentication. Bitwarden differentiates through open-source transparency, client-side encryption, fast enterprise deployment (70% live in under a month), and a freemium model that converts users to paid plans.

Aztec is a privacy-first Layer 2 rollup for Ethereum that enables encrypted transaction execution and private smart contracts while maintaining public verifiability through zero-knowledge proofs. Unlike privacy blockchains like Zcash, Aztec is programmable—developers can specify privacy at granular levels (users, data, metadata, or full contract logic) using the Noir language. It uses client-side proof generation to keep sensitive data off centralized servers, enabling institutions and users to conduct confidential DeFi operations on Ethereum.
