Proton Pass is the password manager offered by Proton AG (Geneva). It encrypts all user data (passwords, passkeys, notes) end-to-end on the client side, so that only the user can decrypt it. It includes features like secure sharing, password generation, passkey support, and dark web monitoring. Proton states that Pass is “trusted by millions” of its users. The service provides apps and browser extensions for cross-device sync. As with other Proton products, emphasis is on privacy and Swiss jurisdiction, though the site itself does not detail Proton’s founding year (2013).
