Proton Pass at a glance

Checked 15 Oct 2026

Proton Pass is a hosted password manager. Its Android, iOS, shared Rust core and CLI clients are GPL-3.0 on GitHub (the web and browser extension code is in Proton's WebClients repo), but the server is not open, so you need a Proton account and cannot self-host. Apps exist for Windows, macOS, Linux, iOS, Android and major browsers. Cure53 audited the mobile apps, browser extensions and API; Proton says all issues but one medium finding were fixed. Some features need a paid Proton plan.
