Bitwarden vs Proton Pass
Both are free/open-source alternatives to 1Password. Here's how they stack up — verified facts, no spin.
Bitwarden
Open-source password manager with optional self-hosting.
Bitwarden is a mature, audited, open-source password manager. Use its low-cost hosted plan or self-host the server for full control, with clients on every platform.
Proton Pass
End-to-end encrypted password manager from the Proton privacy suite.
Proton Pass is a hosted, end-to-end encrypted password manager (passwords, passkeys, 2FA codes, and hide-my-email aliases) from the Swiss privacy company Proton. Its apps are open-source and independently audited, but the service runs on Proton's servers — you can't self-host it. It's the easy, no-server option for people who want strong privacy without running infrastructure.
