OneckPass vs Keeper: Detailed Comparison 2026
Keeper and OneckPass are both robust password managers, but with important differences in encryption (Argon2id vs PBKDF2), pricing, and included features. See the full comparison.
OneckPass vs Keeper: Detailed Comparison 2026
Choosing a password manager is a decision that directly impacts the security of your personal and professional data. In this comparison, we put OneckPass and Keeper side by side -- two password managers that share a rigorous security philosophy but differ in crucial technical aspects.
If you are evaluating which one to adopt in 2026, this analysis will help you make the best decision based on facts, data, and real technical specifications.
Overview: Who Is Who
Keeper
Keeper was founded in 2011, in Chicago (USA). It is a closed-source password manager widely adopted in corporate environments. One of its greatest strengths is the fact that it has never suffered a data breach in its entire history -- a remarkable achievement in the security industry.
Keeper is also recognized by Gartner for its KeeperPAM (Privileged Access Management) solution, which includes session recording, automatic password rotation, and just-in-time access.
OneckPass
OneckPass is a zero-knowledge password manager with end-to-end encryption, available on Web, Chrome, Firefox, Mobile (iOS/Android), and Desktop (macOS/Windows). It uses AES-256-GCM with Argon2id as its key derivation function (KDF), considered the state of the art in brute-force attack protection.
OneckPass's technical differentiator lies in its architecture: the server never has access to plaintext data or the user's master password.
Security and Encryption Comparison
This is the most important aspect of any password manager. Let's dive into the technical details:
| Aspect | OneckPass | Keeper |
|---|---|---|
| Encryption | AES-256-GCM | AES-256 |
| KDF (Key Derivation) | Argon2id | PBKDF2-SHA256 (100k+ iterations) |
| Zero-Knowledge | Yes | Yes |
| Breach History | None | None |
| Source Code | Closed | Closed |
| Certifications | In development | FedRAMP, SOC2, ISO 27001 |
Why Argon2id Matters
The key derivation function (KDF) is the mechanism that transforms your master password into a cryptographic key. PBKDF2-SHA256, used by Keeper, was designed in an earlier era and is vulnerable to attacks with specialized hardware (GPUs and ASICs).
Argon2id, used by OneckPass, won the Password Hashing Competition in 2015 and was specifically designed to be resistant to attacks with specialized hardware. It requires large amounts of RAM (64 MB in OneckPass's case), making brute-force attacks exponentially more expensive.
In practice, this means that even if an attacker obtains your password hash, cracking it on OneckPass would be orders of magnitude more difficult than on Keeper.
If cutting-edge cryptographic security is a priority for you, OneckPass offers a concrete technical advantage with Argon2id.
Pricing Comparison
One of the most relevant points for anyone deciding: the cost. Here is the updated comparison:
| Plan | OneckPass | Keeper |
|---|---|---|
| Free | 50 items, 2 vaults, 50 MB, TOTP | Only 10 passwords |
| Personal/Premium | R$ 9.90/mo or R$ 99/yr | US$ 1.67/mo (~R$ 9.70/mo) |
| Family | R$ 19.90/mo or R$ 199/yr (6 users) | US$ 3.54/mo (~R$ 20.60/mo) for 5 users |
| Business | R$ 29.90/user/mo | US$ 3.75/user/mo (~R$ 21.80/user/mo) |
| Enterprise | Contact sales (50+ members, SLA) | US$ 5+/user/mo |
What the Numbers Reveal
Individual prices are very similar. However, there are important differences:
Free Plan: OneckPass offers 50 items and 2 vaults for free. Keeper limits you to just 10 passwords, which is insufficient for most users.
Breach Monitoring included: In OneckPass Premium, breach monitoring is included at no additional cost. In Keeper, the equivalent feature -- BreachWatch -- costs US$ 20/year extra.
Payment in BRL: OneckPass accepts payment via Mercado Pago (PIX, card, and boleto), without exposure to exchange rate fluctuations. Keeper charges in US dollars.
Family: OneckPass includes 6 users in the family plan, while Keeper includes 5.

Where Keeper Excels
Keeper shines in enterprise environments with KeeperPAM. If your company needs privileged session recording, automatic credential rotation, and just-in-time access, Keeper is one of the best options on the market. It is recognized by Gartner in this category and holds certifications such as FedRAMP, SOC2, and ISO 27001.
Where OneckPass Excels
OneckPass differentiates itself through more modern encryption (Argon2id), a more generous free plan, breach monitoring included in Premium, and an experience optimized for the Brazilian market -- with prices in BRL, PIX payment, and a native Portuguese interface.
User Experience
OneckPass
OneckPass offers a consistent experience across all platforms: Web, Chrome and Firefox extensions, mobile apps for iOS and Android, and desktop apps for macOS and Windows. Cross-device sync is automatic and available on all plans, including the free tier.
The interface is clean and straightforward, with organization by vaults and folders. Data import from other managers makes migration easy.
Keeper
Keeper has a mature and polished interface, the result of over a decade of development. It supports a wide range of browsers and platforms, including Linux. The enterprise experience is particularly robust, with an advanced admin console.
Who Is Each One Ideal For
Choose Keeper if:
- Your company needs PAM (Privileged Access Management) with session recording
- You need compliance certifications such as FedRAMP and SOC2
- Your corporate environment requires automatic credential rotation
- You value the platform's zero breaches track record
Choose OneckPass if:
- You prioritize cutting-edge encryption with Argon2id
- You want a functional free plan (50 items, 2 vaults, TOTP)
- You prefer to pay in BRL without exchange rate fluctuations
- You want breach monitoring included at no additional cost
- You are looking for a native Portuguese experience for the Brazilian market
- You want PIX, card, or boleto as payment options
Verdict: Which One to Choose in 2026?
Keeper and OneckPass are both excellent security options. Neither has suffered breaches, and both implement zero-knowledge architecture.
The difference is in the details: OneckPass uses Argon2id (technically superior to Keeper's PBKDF2), includes breach monitoring at no extra cost, offers a 5x more generous free plan, and charges in BRL with Brazilian payment methods.
Keeper, in turn, has the advantage in enterprise with KeeperPAM and holds compliance certifications that may be required in regulated sectors.
For personal use and small teams, OneckPass delivers more value for the same investment. For large corporations with PAM needs, Keeper deserves consideration.
