Again, LastPass doesn’t see or store your master password, meaning even if your account data is stolen, the attacker won’t have the necessary key to decrypt your encrypted vault. LastPass doesn’t go as far, offering just the single AES-256 key for protection (read our description of encryption for more on that). The other is a device key that’s generated based on hardware and software specifications when you add a new device to your account. One of them is your master password, which 1Password never sees or stores. It has a more unique approach to security that could protect your logins in the event of a breach.ġPassword uses a two-secret-key security model, meaning there are two encryption keys required to unlock your passwords.

That said, there are reasons you should use 1Password vs LastPass. LastPass and 1Password are evenly matched in terms of security, both offering excellent encryption and a zero-knowledge model.
