Why LastPass users are leaving
LastPass's 2022 breaches exposed encrypted vaults along with metadata that helps attackers prioritize targets. Because LastPass uses PBKDF2 (often with low iteration counts on older accounts), attackers can brute-force exposed vaults offline at a rate that's economically viable for high-value targets.
PassCryp uses Argon2id — memory-hard, GPU/ASIC-resistant — at OWASP-recommended parameters (64 MB memory, 3 iterations). The same brute-force budget that yields thousands of LastPass guesses per second yields a handful per second against PassCryp. The economics flip entirely.
