What is the best free password manager?
Bitwarden is the best free password manager: unlimited passwords and passkeys on all your devices, open source and regularly audited, with no catches. Proton Pass Free is the strong alternative and throws in ten free email aliases.
Bitwarden Free is that rare thing: free with no trapdoor underneath. No device limit, no password limit, passkeys included, and the same zero-knowledge security as the paid tier. Because the code is open source and the company earns from paid and business subscriptions, the business model is transparent. For most people this is everything they will ever need.
Proton Pass Free sits right behind it with a unique extra: ten email aliases that keep your real address out of store databases. Also open source, also audited, also unlimited devices. If you already use Proton Mail or Proton VPN, this is the natural vault.
Skip the free plans that are mostly bait (one device at a time, or choosing between mobile and desktop) and the built-in browser managers as a final destination. And upgrading stays cheap: Bitwarden Premium costs $10 a year, roughly the best value in all of security software.
