Ugh.
I get why two-factor authentication is important, but holy hell.
There are SO MANY services that I seldom use (mainly for work) that force me to re-authenticate EVERY TIME I USE THEM because it's passed some threshold of time since the last usage.
And why bother adding a "trust this browser" or "don't show this again" checkbox when you're obviously going to ignore it and ask again next time anyway?
