VERIFIEDSwiss zero-knowledge password manager (Proton AG / Proton Foundation), open-source apps + extensions, Cure53-audited, free unlimited tier.
Why this score?
Proton Pass is part of the Proton AG product portfolio (Plan-les-Ouates, Geneva, Switzerland) — controlled since 2024 by the non-profit Proton Foundation which structurally shields the company from VC/PE acquisition. Launched June 2023 as freemium with open-source apps and browser extensions on GitHub, audited by Cure53 in 2023 (full audit, no critical issues), end-to-end zero-knowledge encryption, account data stored exclusively in Switzerland/Germany/Norway alongside the rest of the Proton estate — gold-standard 5/5 with no CLOUD Act exposure, mirroring the Proton VPN posture.
