What is Proton Pass?
Proton Pass is an encrypted password manager developed by the Swiss-based company Proton AG, best known for privacy-focused services like Proton Mail and Proton VPN. It generates, stores, and auto-fills complex passwords and other sensitive data such as email aliases and two-factor authentication (2FA) codes.
Its defining characteristic is deep integration with Proton's philosophy of security and privacy by design. End-to-end encryption ensures that only the user can ever access their stored credentials.
The application is built upon the same open-source, audited, and zero-knowledge encryption principles that underpin Proton's email service. All encryption and decryption of your password vault happens locally on your device. Not even Proton's servers can see your passwords, usernames, notes, or other stored items.
This positions Proton Pass not just as a utility for convenience, but as a security-centric tool for users who prioritise data sovereignty and are wary of cloud-based services with potential backdoor access.
Who is Proton Pass best for?
Proton Pass is not a one-size-fits-all solution. Its design and pricing structure make it particularly compelling for specific user profiles.
It shines for individuals already invested in the Proton ecosystem or who place an absolute premium on privacy and the technical assurance of open-source, zero-knowledge architecture. It is less suited for those seeking the most polished, feature-rich, or family-friendly experience on the market.
- Existing Proton Users: Individuals or families already paying for Proton Unlimited or another Proton plan get Proton Pass included, making it a logical step for consolidating privacy tools.
- Privacy Advocates: Users deeply concerned with data collection and who prefer services with a proven, transparent commitment to zero-knowledge encryption and open-source code.
- Security-Minded Individuals: Those who appreciate integrated 2FA code generation and the unique Proton-specific feature of Hide-my-email aliases directly within the password manager interface.
- Solo Professionals or Tech Enthusiasts: Users comfortable with capable but sometimes less refined apps, who prioritise underlying security architecture over some convenience features found in more established competitors.
Key features
End-to-End Encrypted Vault
Every piece of data stored in Proton Pass — passwords, notes, aliases, even the URLs of saved sites — is encrypted on your device before it is synced to Proton's servers. The encryption uses your master password, which is never sent to or stored by Proton.
This zero-knowledge model is fundamental. A breach of Proton's servers would not compromise your vault's contents.
Integrated Proton Mail Aliases (Hide-My-Email)
This standout feature integrates tightly with a Proton Mail account. It allows you to generate unique, random email aliases (e.g., [email protected]) on the fly when signing up for new online services.
These aliases forward to your real Proton Mail inbox, shielding your primary email address from spam, data breaches, and tracking. Managing these aliases is done directly within the Proton Pass interface.
Built-in Two-Factor Authenticator (2FA)
Proton Pass can generate time-based one-time passwords (TOTP) for websites that support 2FA. This means your second-factor codes are stored in the same encrypted vault as your passwords, allowing for auto-fill of both credentials from a single app.
While convenient, storing your 2FA seeds in the same place as your passwords slightly reduces the security principle of separation of concerns. It remains protected by the vault's encryption.
Secure Notes and Credit Card Storage
Beyond passwords, the vault can store free-form secure notes for information like software licences, Wi-Fi passwords, or other sensitive text. It also includes dedicated fields for storing credit or debit card details, which can be auto-filled during checkout processes.
Browser extension support for card autofill can be less consistent than with dedicated financial autofill tools.
Open-Source and Audited Code
The code for Proton Pass's core cryptography library and applications is publicly available for inspection on GitHub. This transparency allows independent security experts to audit the code for vulnerabilities.
Proton also commissions regular third-party security audits, the reports of which are published.
Proton Pass pricing
Proton Pass employs a tiered pricing model that is deeply integrated with the broader Proton service suite. A limited free plan is available, which includes access on unlimited devices, storage of up to 20 passwords, 10 hide-my-email aliases, and unlimited secure notes.
For full functionality, you must subscribe to a paid Proton plan.
| Plan | Price (annual billing) | What's included |
|---|---|---|
| Free | £0 | Unlimited devices, 20 passwords, 10 aliases, unlimited notes |
| Pass Plus | £3.19/month | Unlimited passwords, aliases, 2FA items, priority support |
| Proton Unlimited | £11.99/month | Pass Plus features plus 500GB Drive, Mail with custom domains, Calendar, VPN |
The standalone Pass Plus plan faces stiff competition on price from more mature managers. The Proton Unlimited bundle represents exceptional value for anyone wanting a full, private digital ecosystem from a single provider.
Bottom line: Proton Pass is a top-tier choice for privacy-centric users, especially those already within the Proton ecosystem. It excels at keeping credentials private and secure.
What we like
- Zero-knowledge encryption: The strict, verifiable end-to-end encryption provides a high degree of trust and security for all vault data.
- Hide-my-email integration: The seamless integration of alias creation and management is a uniquely powerful privacy feature not commonly found in password managers.
- Built-in 2FA: Including a 2FA authenticator within the encrypted vault offers significant convenience for daily use.
- Open-source transparency: Published third-party audits offer a level of transparency that is still rare in commercial software.
- Value for Proton users: Adding a fully-featured password manager to an existing subscription represents outstanding added value at no extra cost.
What could be better
- Less polished interface: The user interface and browser extension, while functional, can feel less polished and slightly slower than leading competitors like 1Password or Bitwarden.
- No business features: It lacks advanced features for team or business use, such as administrative controls, group policies, and streamlined user provisioning.
- Basic sharing: Sharing capabilities for passwords or secure items with other users are very basic or non-existent compared to rivals.
- Inconsistent autofill: Browser autofill and capture functionality can occasionally be inconsistent, sometimes requiring manual intervention.
Proton Pass verdict
Proton Pass is a compelling and highly secure password manager that makes the most sense within the context of Proton's broader privacy ecosystem. Its strengths are foundational: impeccable encryption standards, transparency through open-source code, and innovative privacy features like integrated email aliases.
For the individual user who prioritises these principles above all else, particularly if they are already a Proton subscriber, it is an easy and powerful recommendation. The bundled value within the Proton Unlimited plan is arguably unmatched for a suite of privacy tools.
However, it is not yet the most rounded or user-friendly password manager on the market. Those who need seamless sharing with family members, advanced business features, or who simply want the most polished and consistently reliable autofill experience may find more satisfaction with established alternatives like 1Password or Bitwarden.
Who should buy: Privacy advocates and existing Proton subscribers. Who should look elsewhere: Families needing sharing tools or users wanting the most polished autofill experience.
Proton Pass excels at its core mission of keeping your credentials private and secure, but it is still maturing in terms of delivering the seamless convenience that defines the best in the category.
