Proton Pass Review 2026: Open-Source Password Manager Worth Trying?
Proton Pass is a solid, genuinely private password manager from a company with real privacy credentials. Open-source, end-to-end encrypted, and well-priced — especially for existing Proton users. Not quite as polished as 1Password, but a trustworthy option that's improving fast.
Proton Pass launched in 2023 as the newest addition to the Proton ecosystem. It’s younger than 1Password or Bitwarden, but it’s built on the same privacy principles that made Proton Mail trusted by millions — and it’s improving with every update.
What Proton Pass Does Well
Security and Privacy
Proton Pass uses end-to-end encryption for everything in your vault — passwords, notes, card details, and identities. Unlike some competitors, it also encrypts metadata (website names, usernames) not just the password itself. Most password managers only encrypt the password field; Proton encrypts everything.
Key security features:
- AES-256 + bcrypt encryption — strong, well-regarded implementation
- End-to-end encrypted metadata — competitors often leave this unencrypted
- Open-source — all apps are publicly auditable
- Swiss jurisdiction — Proton AG is based in Geneva
- Independently audited by Cure53 (2023)
Hide-My-Email Aliases
This is Proton Pass’s standout feature. When signing up for any website, you can generate a unique email alias (e.g., randomword.randomword@pm.me) that forwards to your real inbox. The website never sees your real email address.
This stops spam at the source and makes it impossible to track you across services using your email. It’s similar to Apple’s “Hide My Email” but works with any email provider, not just iCloud.
Price
Proton Pass is well-priced, particularly for existing Proton users. Proton Unlimited (£7.99/month) bundles Pass with Proton Mail, VPN, and Drive — making the effective cost of Pass very low if you’re already paying for other Proton services.
Apps and Autofill
Proton Pass has browser extensions for all major browsers and native apps for iOS and Android. Autofill is reliable on both platforms. The interface is clean and straightforward.
One useful feature: the iOS app supports Face ID / Touch ID unlock, keeping the vault secure without requiring you to type a master password every time.
Pricing
| Plan | Price | Devices |
|---|---|---|
| Free | £0 | 1 device, unlimited passwords |
| Pass Plus | ~£3.99/month | Unlimited devices + aliases |
| Proton Unlimited | ~£7.99/month | Everything in Pass Plus + Mail + VPN + Drive |
What Could Be Better
- Maturity — Proton Pass launched in 2023 and is younger than 1Password or Bitwarden. Some advanced features (travel mode, detailed audit logs, fine-grained sharing) are still catching up
- Business features — the Teams and Business plans are improving but not yet as fully featured as 1Password Teams or Keeper for managed deployments
- Desktop app — there’s no standalone desktop app yet (browser extension only on desktop); a native desktop app is on the roadmap
- Third-party integrations — fewer than 1Password for enterprise/SSO setups
Who Should Use Proton Pass
- Existing Proton users (Proton Unlimited makes it essentially free)
- Privacy-conscious individuals who want open-source, audited software
- Anyone who wants hide-my-email aliases
- Users who don’t need advanced enterprise features
For businesses needing enterprise SSO, detailed audit logs, and IT admin controls, 1Password Teams or Keeper Security remain stronger choices.
Verdict
Rating: 4/5
Proton Pass is a trustworthy, well-built password manager from a company with genuine privacy credentials. The hide-my-email aliases are genuinely useful, the encryption implementation is strong, and the price is excellent — especially as part of Proton Unlimited. It’s not as mature or feature-complete as 1Password, but for individual use it’s a very strong option.
