comment How does LastPass' grid multi-factor authentication work behind the scenes?
Thanks for than link @john. According to the lastpass user manual (helpdesk.lastpass.com/security-options/…) there is an option to allow offline access. Your link seems to suggest is that if you allow this then it is basically possible to circumvent the 2nd factor in an offline context. The only way the 2nd factor works is if you disallow offline access.

comment How does the Windows “Secure Desktop” mode work?
@Iszi thanks for pointing that out. What are hardware keyloggers? Would that be like a specially engineered keyboard in an internet cafe? I'm mostly concerned about my Windows PC so I'm willing to trust that the hardware is fine but I am concerned about Malware installing itself.

comment How does LastPass' grid multi-factor authentication work behind the scenes?
I guess what I was trying to understand and what got me confused is how this works in an offline context. I understand the Challenge-Response model when you are online but Lastpass claims that you can still access you vault when you are offline (I haven't tested this). Any guesses for how the grid authentication works when you are offline?

You're right, I meant to say that the shared secret is the grid, not the key. Apologies for the typo as well as the unclear explanation but I was writing in a hurry. I actually don't know how the Lastpass OTPs work, I was hypothesizing about how I thought it could work.
