As the master password is something I don't frequently use, I do sometimes need to try my combinations, repetitively. Sadly, when LastPass decides my computer is not a verified device, it doesn't say whether if I'm entering my master password wrong, or that if I answered it right but have to also verify my device first to enter.
It turns out I did enter my master password a bunch of times, thinking I didn't, and got locked off of my account for too-many-incorrect attempts. I don't have all day here and I just need to use your service. How long does this "temporary suspension" even take?
