Our verdict: the most thoroughly audited open-source password manager available — a safe default for individuals and teams alike.

Bitwarden is an open-source password manager built on a zero-knowledge, end-to-end encrypted architecture: your vault is encrypted on your device before it ever touches Bitwarden's servers, so not even the company can read it. It covers every surface you work on — desktop apps for Windows, macOS and Linux, mobile apps for iOS and Android, extensions for all major browsers, a full web vault and a CLI — with seamless sync across all of them on the free tier.

What sets Bitwarden apart is verifiability. Every client is published under the GPL-3.0 license on GitHub, and the company commissions annual third-party security audits from firms such as Cure53 and Insight Risk Consulting, publishing the reports openly. The free tier is genuinely usable with unlimited passwords and devices, while Premium adds an integrated authenticator, encrypted file attachments and emergency access for a modest annual fee.
