Yep 2-factor support is new in the latest release and I have not got around to documenting it. Thanks for doing so.
One point to remember is if you are signing up to GVMax using a 2-factor password, GVMax will not be able to automatically create the required GMail filters for you and you will have to do it manually.
Ah! This is fantastic. I'd assumed there was no way to do this with 2-step authentication.
GVMax, I've already registered my Google account on your app, but is it possible to carry out this process ex post facto? I.e., if I wanted to re-implement 2-step on my account, would it just be a matter of changing the password here to whatever app code Google gives me, and would that assuredly remove records of my proper Google password from your server? (Don't let me sound too incredulous when I ask that; your app is clearly awesome [it's the reason I quite nearly did away with my mobile phone altogether!], but I am as big a believer in taking the extra step to secure things as anybody.)
