I gave up on two-factor authentication when I couldn't get Chrome to sync properly across my devices. It was a pain.
Meanwhile, I tried logging in to my Windows Live account today and was told they no longer accepted passwords longer than 16 characters. To be able to log in I had to enter the first 16 characters and leave out the rest (4 characters, in this case). Thought that was... unusual.
