Proton Pass

Our verdict: a rigorously audited, fully open-source password manager with a genuinely useful free tier — the strongest pick if you want your credentials inside the Proton privacy ecosystem.

Proton Pass is the password manager from Proton AG, the Swiss company behind Proton Mail and Proton VPN. It stores logins, notes, credit cards, and passkeys behind end-to-end encryption, and adds identity tools that most rivals charge for — including hide-my-email aliases and a built-in two-factor authenticator. Apps cover Windows, macOS, Linux, iOS, Android, all major browsers, a web vault, and even a command-line interface.

What sets Proton Pass apart is its verifiability. Every client application is published under the GPL-3.0 license on GitHub, and the code has been independently audited twice: by Cure53 in 2023 and by Recurity Labs across January–April 2026, with the latter finding no remote exploits or encryption bypasses and rating its security posture well above par. Backed by Swiss privacy law and a subscription business model rather than advertising, it is a calm, credible home for your most sensitive data.
