Bitwarden is an open-source password manager that securely stores passwords, credit cards, identities, and secure notes in an encrypted vault. Founded in 2016 by Kyle Spearrin, Bitwarden uses AES-256 bit encryption with salted hashing and PBKDF2 to protect user data. The platform supports auto-fill on websites and apps, password generation, two-factor authentication, and secure password sharing. Bitwarden offers a generous free tier with unlimited passwords and device sync, making it one of the most accessible password managers available. The app is fully open-source and has been audited by third-party security firms. Bitwarden is available on every major platform including browser extensions for Chrome, Firefox, Safari, and Edge. Business plans include organizational vaults, user management, and SSO integration.
