These encrypted fields remain secured with 256-bit AES encryption and can only be decrypted with a unique encryption key derived from each user’s master password using our Zero Knowledge architecture. As a reminder, the master password is never known to LastPass and is not stored or maintained by LastPass. The encryption and decryption of data is performed only on the local LastPass client. For more information about our Zero Knowledge architecture and encryption algorithms, please see <a href="https://www.lastpass.com/security/zero-knowledge-security" target="_blank">here.</a></blockquote>
