PassCrypt vs LastPass
Compare PassCrypt and LastPass. Understand how PassCrypt’s zero-knowledge parameters protect against the vulnerabilities exposed in the 2022 LastPass breach.
Specifications Matrix
| Feature | LastPass | PassCrypt |
|---|---|---|
| Derivation Function | PBKDF2-SHA256 (Default) | Argon2id (m=64MB, t=3, p=4) |
| Cryptographic API | Proprietary client wrapper | W3C WebCrypto API (Native) |
| Pricing Structure | $36/yr | Free Tier / $11.99/year |
| Metadata Encryption | Unencrypted (Plaintext URLs) | Full Sitewide Encryption |
| Self-Hostable | Yes | Yes (Vercel/Compose Compose) |
Understanding LastPass’s Framework
LastPass offers key features, but contains architectural variables to consider:
- •History of critical database breaches
- •Unencrypted vault metadata (e.g. target URLs)
- •Legacy accounts locked with low iteration limits
The PassCrypt Advantage
PassCrypt encrypts every single vault field, including URLs and metadata. We enforce memory-hard Argon2id derivation to ensure stolen vaults cannot be cracked on GPU clusters, and run on pure native WebCrypto.
- Default memory-hard Argon2id key generation
- Zero third-party cryptographic npm dependencies
- Three times more affordable premium options
Frequently Asked Questions
Could PassCrypt suffer a breach similar to LastPass?
In a complete server compromise, an attacker could steal PassCrypt's encrypted vault blobs. However, the outcomes would differ entirely. First, PassCrypt encrypts all vault metadata (including URLs and folder names), so attackers cannot identify high-value targets. Second, because PassCrypt enforces memory-hard Argon2id key derivation, a GPU rig testing master passwords is throttled to 2-4 guesses per second (vs 42,000+ guesses/sec on LastPass vaults). For strong master passwords, cracking is computationally impossible.
