OneckPass vs LastPass: Security and Trust in 2026
After the massive 2022 breaches, LastPass lost the trust of millions of users. OneckPass uses Argon2id (vs LastPass's PBKDF2), zero-knowledge architecture from day one, and has never suffered a breach.
OneckPass vs LastPass: Security and Trust in 2026
LastPass was, for years, the most popular password manager in the world. With millions of users and a presence on virtually every "best password managers" list, it seemed like a safe choice.
Until 2022.
That year, LastPass suffered a series of massive breaches that resulted in the compromise of user vaults -- the encrypted data that should have been secure was exfiltrated. Since then, LastPass has been trying to rebuild lost trust, but the question remains: would you trust your most sensitive data to a service that has already been compromised?
In this comparison, we analyze LastPass and OneckPass based on facts, technical specifications, and verifiable data.
The Elephant in the Room: The 2022 Breaches
Let's start with what really matters. In 2022, LastPass revealed that:
August 2022: An attacker gained access to LastPass's development environment, compromising source code and proprietary technical information.
November 2022: Using information obtained from the first incident, the attacker accessed backups of user vaults stored in the cloud. This included encrypted data (passwords) and unencrypted data (website URLs, company names, usernames, email addresses, phone numbers, and IP addresses).
The real impact: The exfiltrated encrypted vaults contain passwords protected by AES-256 encryption with PBKDF2. The problem? Users with weak master passwords and older accounts (with only 5,000 PBKDF2 iterations) were especially vulnerable to brute-force attacks.
In December 2023, security researchers publicly linked cryptocurrency thefts worth millions of dollars to LastPass vaults that were compromised in this breach.
This is not a theoretical risk. These are real, documented financial losses attributed to the LastPass breach.
And OneckPass?
OneckPass has never suffered a data breach. Its zero-knowledge architecture was designed from day one to ensure that, even in a hypothetical server compromise scenario, user data remains protected.
Encryption Comparison
A password manager's security fundamentally depends on two elements: the encryption algorithm and the key derivation function (KDF).
| Aspect | OneckPass | LastPass |
|---|---|---|
| Encryption | AES-256-GCM | AES-256-CBC |
| KDF | Argon2id (memory-hard) | PBKDF2-SHA256 (100,100 iterations) |
| Random IV per operation | Yes (12 bytes) | Yes |
| Zero-Knowledge | Yes | Yes (but vaults were exfiltrated) |
| Breach History | None | Massive breaches in 2022 |
PBKDF2 vs Argon2id: The Technical Difference That Matters
LastPass uses PBKDF2-SHA256 with 100,100 iterations. This algorithm is purely CPU-based, meaning attacks can be accelerated with GPUs and ASICs -- hardware that is widely available and increasingly affordable.
OneckPass uses Argon2id with:
- 3 iterations
- 64 MB of mandatory memory
- 4 parallelism threads
Argon2id is memory-hard: each brute-force attempt requires 64 MB of dedicated RAM. This makes massively parallel attacks with GPUs economically unfeasible, since GPUs have limited memory per core.
To put it in perspective: an attacker with US$ 10,000 worth of hardware could test orders of magnitude more combinations per second against PBKDF2 than against Argon2id.
AES-256-GCM vs AES-256-CBC
OneckPass uses AES-256-GCM (Galois/Counter Mode), which provides encryption and integrated authentication. LastPass historically used AES-256-CBC, which requires separate mechanisms to ensure data integrity.
Pricing Comparison
| Plan | OneckPass | LastPass |
|---|---|---|
| Free | 50 items, 2 vaults, 50 MB, TOTP, multi-device sync | 1 device type only |
| Premium | R$ 9.90/mo or R$ 99/yr | US$ 3/mo (~R$ 17.40/mo) |
| Family | R$ 19.90/mo or R$ 199/yr (6 users) | US$ 4/mo (~R$ 23.20/mo) for 6 users |
| Business | R$ 29.90/user/mo (SSO, API) | US$ 4.25+/user/mo (~R$ 24.70/user/mo) |
| Payment | PIX, card, boleto (BRL) | International card (USD) |
Cost Analysis
LastPass is significantly more expensive than OneckPass across all plans:
- Premium: OneckPass costs R$ 9.90/mo. LastPass costs ~R$ 17.40/mo. 43% savings with OneckPass.
- Family: OneckPass costs R$ 19.90/mo. LastPass costs ~R$ 23.20/mo. 14% savings with OneckPass.
- Free: OneckPass allows 50 items on any device. LastPass restricts to a single device type (phone only or computer only), making the free plan practically unusable.
Additionally, OneckPass charges in Brazilian reais with payment via Mercado Pago (PIX, card, boleto), eliminating exchange rate exposure.

OneckPass Highlights
- Multi-device sync on the Free plan: While LastPass restricts free users to one device type, OneckPass allows full sync on all plans.
- Free TOTP: Two-factor authentication (TOTP) is available on OneckPass's Free plan. On LastPass, it is a Premium feature.
- Native desktop app: OneckPass offers a desktop application for macOS and Windows, with universal autofill.
The Trust Question
Security is not just about algorithms and protocols. It is about trust. And trust, once lost, is extremely difficult to rebuild.
What the 2022 breach revealed about LastPass
- URLs were not encrypted: The websites users visited were stored in plaintext, exposing browsing habits and potential targets.
- Inconsistent PBKDF2 iterations: Older accounts had only 5,000 iterations (vs the current 100,100), and LastPass did not force an update before the breach.
- Slow communication: LastPass took months to reveal the full extent of the incident.
OneckPass's approach
OneckPass was built on the premise that the server is a potential compromise point. Therefore:
- The encryption key is never transmitted to the server
- The server stores only encrypted blobs
- The authentication hash is derived separately from the encryption key
- When the user locks or logs out, the key is zeroed from memory (
encryptionKey.fill(0))
Even if the entire OneckPass database were exfiltrated, attackers would have only data encrypted with AES-256-GCM, protected by keys derived with Argon2id. Without each user's master password, this data is computationally impossible to decrypt with current technology.
Who Should Still Consider LastPass
In the interest of honesty, LastPass has some points that may be relevant:
- Maturity: With nearly two decades of operation, LastPass has an extensive knowledge base and broad compatibility
- Custom item types: LastPass allows creating custom item types beyond the standard ones
- Separate authenticator: LastPass Authenticator is a separate app for 2FA
However, none of these points compensate for the fundamental trust issue after the 2022 breaches.
How to Migrate from LastPass to OneckPass
Migration is straightforward and takes just a few minutes:
- In LastPass: Go to Advanced Options > Export (you will receive a CSV file)
- In OneckPass: Create your account at oneckpass.com
- Import: Use OneckPass's import function
- Verify: Check that all items were imported
- Install: Download extensions and apps
- Deactivate LastPass: After verifying everything is working, remove LastPass
Security tip: After importing, delete the exported CSV file. It contains your passwords in plaintext.
