OneckPass vs Proton Pass: Privacy and Security Compared
An honest comparison between OneckPass and Proton Pass. We analyze encryption, privacy, pricing, platforms and features to help you choose the best password manager between two security-focused options.
OneckPass vs Proton Pass: Privacy and Security Compared
When it comes to digital privacy, few names carry as much credibility as Proton. Creator of ProtonMail in 2014, the Swiss company became synonymous with data protection. In 2022, it launched Proton Pass, its password manager that quickly gained traction in the market.
In this comparison, we will put Proton Pass side by side with OneckPass, a zero-knowledge password manager with end-to-end encryption, prices in BRL and a focus on the Brazilian audience. The goal here is to be honest: acknowledge where each solution excels and help you make the best choice for your scenario.
Overview: Who Is Who
Proton Pass
Proton Pass was launched in 2022 by Proton AG, a company founded in 2014 by CERN scientists in Geneva, Switzerland. It operates under Swiss jurisdiction, known for its strict privacy laws, and has open-source code under the GPLv3 license, allowing anyone to audit the source code. It is part of a complete ecosystem that includes ProtonMail, Proton VPN, Proton Drive and Proton Calendar.
OneckPass
OneckPass is a zero-knowledge password manager with end-to-end encryption, developed with a focus on the Brazilian and Latin American market. It offers prices in BRL, native Portuguese support and a functional free plan. It is available on Web, Chrome and Firefox extensions, mobile app (iOS and Android) and native desktop (macOS and Windows).
Security and Privacy Comparison
If you are comparing these two products, security and privacy are likely your most important criteria. Let's get straight to the technical details:
| Criterion | OneckPass | Proton Pass |
|---|---|---|
| Encryption | AES-256-GCM | AES-256-GCM |
| Key Derivation (KDF) | Argon2id | Argon2 |
| Architecture | Zero-knowledge | Zero-knowledge |
| Encrypted metadata | Item data | Everything (including names and URLs) |
| Code | Closed | Open (GPLv3) |
| Jurisdiction | Brazil | Switzerland |
What does this mean in practice?
Both use AES-256-GCM and key derivation based on Argon2, the state of the art in protection against brute force attacks. In terms of pure encryption, they are on the same level.
Proton Pass stands out for encrypting absolutely everything, including metadata such as item names and URLs. Most password managers only encrypt sensitive fields (passwords, notes), but Proton Pass goes further. Additionally, it features Proton Sentinel, an AI-powered security system that monitors and blocks suspicious access attempts.
OneckPass adopts a pure end-to-end encryption approach: the encryption key never leaves the user's device, and the server never has access to plaintext data. The master password combined with the user's email goes through Argon2id, generating two separate keys: one for authentication and one for encryption.
Proton Pass's open-source code is an objective advantage in transparency. Any security researcher can audit the code and verify that it does what it promises.
Security verdict: Proton Pass has an advantage in transparency (open source) and metadata encryption. Both offer robust protection for your data.
Price Comparison
Here the differences become relevant, especially for those living in Brazil:
| Plan | OneckPass | Proton Pass |
|---|---|---|
| Free | R$ 0 (50 items, 2 vaults, 50MB, TOTP) | Free (UNLIMITED passwords and devices) |
| Individual | R$ 9.90/month or R$ 99/year | US$ 2.49/month (~R$ 14.50) |
| Family | R$ 19.90/month or R$ 199/year (6 users) | US$ 4.99/month (~R$ 29) for 6 users |
| Full bundle | N/A | US$ 9.99/month (VPN + Email + Drive + Calendar) |
| Payment | PIX, card, boleto (Mercado Pago) | International credit card |
Free plan: Proton Pass advantage
It's important to be honest: the Proton Pass free plan is the best on the market. Unlimited passwords, unlimited devices, no artificial restrictions. OneckPass's Free plan is functional with 50 items and 2 vaults, but it does not compete with Proton Pass's generosity in this regard.
Paid price: OneckPass advantage for Brazilians
If you need premium features, the equation changes. Proton Pass Plus costs US$ 2.49/month, which equals approximately R$ 14.50, plus 4.38% IOF tax and possible international card fees, easily reaching R$ 16 or more per month.
OneckPass Premium costs R$ 9.90/month or R$ 99/year, with payment via PIX, national card or boleto. This represents savings of over 30% without the hassle of international payment.

Platform Comparison
| Platform | OneckPass | Proton Pass |
|---|---|---|
| Web | Yes | Yes |
| Chrome | Yes | Yes |
| Firefox | Yes | Yes |
| Safari | Coming soon | Yes |
| iOS | Yes | Yes |
| Android | Yes | Yes |
| macOS (Desktop) | Yes (native app) | No (uses web) |
| Windows (Desktop) | Yes (native app) | No (uses web) |
| Linux | Coming soon | No (uses web) |
Native desktop: OneckPass advantage
Here is an important difference that many overlook: Proton Pass does not have a dedicated desktop application. To use it on a computer, you rely on the browser or the extension. OneckPass offers a native desktop app for macOS and Windows, built with Tauri 2, that runs directly on the operating system with universal autofill for any application.
If you need to fill passwords in applications outside the browser (such as email clients, banking apps, development tools), the native desktop app makes a difference in daily use.
Feature Comparison
| Feature | OneckPass | Proton Pass |
|---|---|---|
| Item types | Login, Card, Note, Identity | Login, Card, Note, Identity |
| Vaults | Yes | Yes |
| Folders | Yes | No |
| Sharing | Yes | Yes |

| TOTP (2FA) | Yes (including Free) | Yes |
| CLI | In development | Yes |
| Breach monitoring | Yes (Premium) | Yes |
| Proton Sentinel (AI) | N/A | Yes |
Emergency Contacts: OneckPass exclusive
Proton Pass does not offer emergency access. If something happens to you, there is no native mechanism for a trusted person to access your credentials. OneckPass has built-in Emergency Contacts, allowing you to designate people who can access your data after a configurable waiting period.
This feature is not a minor detail. It is a layer of protection for your digital life that many people only realize they need when it is already too late.
Email aliases: Proton Pass exclusive
Proton Pass offers unlimited email aliases on the Premium plan, a powerful feature for those who want to protect their real email when signing up for services. Each sign-up can use a different alias, reducing spam and increasing privacy. OneckPass does not yet offer this feature.
Who Should Choose Proton Pass?
Proton Pass is the best choice if you:
- Already use the Proton ecosystem (ProtonMail, VPN, Drive)
- Value open source code and auditability
- Want the best free plan on the market (unlimited)
- Need email aliases to protect your email

Conclusion
Proton Pass is an excellent password manager, especially for those already part of the Proton ecosystem or who value open source and Swiss jurisdiction. Its free plan is the most generous on the market, and features like email aliases and Proton Sentinel put it in a prominent position.
For Brazilians, however, OneckPass offers significant practical advantages: prices in BRL up to 30% cheaper, payment via PIX or boleto, native Portuguese support, a dedicated desktop app and Emergency Contacts. These are differences that impact the daily life of those who live and work in Brazil.
The choice between the two depends on your priorities. If absolute privacy and an integrated ecosystem are what matters most, Proton Pass. If fair pricing in BRL, local support and a native desktop experience are the priority, OneckPass.
