Proton Pass: sovereignty score and 8 European alternatives

Proton Pass is a password manager from Proton AG. It keeps passwords, passkeys, credit cards, notes and 2FA codes in encrypted vaults, using zero-knowledge end-to-end encryption: Proton says it cannot access the data unless you share it. There are apps for Windows, macOS, Linux, Android and iOS, a web app, browser extensions for Chrome, Firefox, Safari, Edge and Brave, and a command-line tool. It also offers hide-my-email aliases and vault sharing. The service is delivered as SaaS.

Proton AG is based in Plan-les-Ouates near Geneva, Switzerland, an EFTA country outside the EU. According to its privacy policy, data is stored encrypted on servers located exclusively in Switzerland, Germany or Norway and owned by Proton or its subsidiaries. Part of the alias feature runs on European cloud servers of the subsidiary SimpleLogin SAS. The client source code has been open source under the GPLv3 since July 2023 and was audited by Cure53.

Why digital sovereignty matters with Proton Pass

Proton Pass is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Proton Pass hosts data in the EU and in Switzerland. Switzerland is covered by a European Commission adequacy decision, so personal data can go there without extra safeguards. If you require strictly EU hosting, check the data processing agreement for which data is stored in Switzerland.

Proton Pass is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Proton Pass together with your other vendors and gives a total score, a heatmap and the main risk drivers.
