Proton Pass comes from the Swiss company behind Proton Mail and it stores logins, notes, and cards with end-to-end encryption. Its standout feature is built-in email aliasing via SimpleLogin, which lets you hand out a different address to every site so your real email stays private. The apps are open source and passed an independent audit by Cure53, with a further review by Recurity Labs completed in 2026. Being based in Switzerland puts it under relatively strong privacy law and Proton accepts Bitcoin for payment. It's a strong pick if you're already in the Proton ecosystem or want aliasing and a password manager in one place.
