Late reply, but for me personally, I started doing it because my Keepass database is already accessed using two factors (password and key file). Therefore, I’d gain very little by keeping the second factor of those sites external - essentially, those second factors are compounded into the second factor for the database.
Not only is that headline’s grammar exceptional(ly bad), for a moment I thought the developer of Control was named Alan Wake. Like, how did they manage to butcher that so badly?
