Bitwarden – Open Source Password Manager with Zero-Knowledge Encryption
Overview
Bitwarden is the leading open-source password manager trusted by security professionals, enterprises, and privacy advocates worldwide. Built with a zero-knowledge architecture and end-to-end AES-256 bit encryption, Bitwarden ensures that even the company itself cannot access your passwords – only you hold the keys to your vault. The open-source codebase has been independently audited by security firms including Cure53, and is publicly available on GitHub for full transparency. Bitwarden offers native applications for Windows, macOS, Linux, iOS, Android, and browser extensions for Chrome, Firefox, Safari, Edge, and more. The free tier is surprisingly generous, offering unlimited passwords, unlimited devices, secure password sharing, and cross-platform sync – features that competitors charge for. Premium features include encrypted file attachments (1GB storage), TOTP authenticator, advanced 2FA options (YubiKey, Duo, FIDO2), breach monitoring, vault health reports, and priority support for just $10/year. For teams and businesses, Bitwarden offers self-hosted deployment options, allowing you to maintain complete control over your infrastructure. The password generator creates cryptographically strong passwords up to 128 characters, while the autofill feature seamlessly integrates with websites and apps. Security professionals appreciate Bitwarden’s commitment to transparency, regular security updates, and extensive API for automation.
