Verdict: LastPass suffered one of the worst security breaches possible for a password manager: attackers stole encrypted vaults. While vaults remain encrypted, weak master passwords make them crackable. Most security experts now recommend switching to alternatives.
LastPass is one of the most popular password managers with millions of users. However, a catastrophic 2022 breach exposed encrypted password vaults, fundamentally undermining trust in the service.
