Open-source password managers can be independently audited and (in Bitwarden's case) self-hosted. If you want maximum transparency about how your passwords are protected, pick from these.
Best Open-Source Password Manager (2026)
Auditable code, self-hostable options, privacy-respecting
1. Bitwarden — our pick
Bitwarden is the open-source standard. Free tier is genuinely usable forever. Paid Premium at $10/year is the cheapest in the industry. Best pick for privacy-focused users and developers who self-host.
2. Proton Pass
Proton Pass is the privacy-focused pick. Swiss jurisdiction, open-source, from the Proton team. Best if you're already in the Proton ecosystem (Mail + VPN + Pass + Drive) — Proton Unlimited at $9.99/mo is excellent value.
