Bitwarden

Bitwarden is an open-source password manager that lets individuals and organizations securely generate, store, and share passwords and other sensitive data across devices, with its full source code publicly auditable, which appeals to security-conscious users who don't want to trust a password manager's security claims without being able to verify them. It supports end-to-end encrypted vaults synced across desktop, browser extension, and mobile apps, generates strong unique passwords for every account, and can autofill login credentials to prevent both weak passwords and phishing attacks that rely on users manually typing credentials into look-alike sites. Bitwarden's business and enterprise tiers add organization-wide vaults for securely sharing credentials among team members, admin controls like enforced password policies and SSO integration, and detailed audit logs for compliance purposes. Because it's open-source, teams with strict security or compliance requirements have the option to self-host Bitwarden on their own infrastructure rather than relying on the company's cloud service, which is a meaningful differentiator from closed-source competitors in regulated industries. A free tier covers unlimited passwords and syncing across unlimited devices for individual users, which has made it one of the most widely recommended password managers among security professionals. Bitwarden is used by individuals, startups, and larger organizations that want strong credential security without vendor lock-in to closed, proprietary software.
