This encryption key remains on the user’s device (and is never received by LastPass) and is used to encrypt vault data with the AES256 algorithm. The LastPass browser extension or mobile application utilizes PBKDF2 with SHA-256 to derive a unique encryption key from a user’s master password.

But would appreciate confirmation of my theory or correction. I’m assuming this is the case if your guidance that somebody would need to be physically present applies.Ģ) When I enter my password, is it possible for that password (or key strokes) to be recorded and used without my knowledge to access my vault? I’m guessing so, hence the benefit of using a second authentication method and controlling allowed mobile devices.

I think you have described how the encryption is done by the device (eg client pc or smart phone) using the password only known at the client end, then sent to the servers for storage (please correct me if I got that wrong).ġ) When my vault is open on my pc and legible (ie I can read it) then is it possible for Malware or somebody snooping on my network to access that deciphered information? Or, once it is written to the screen, is the information encrypted again (ie deciphered information is not held in memory on the device once sent to graphics adapter).
