Having to use your security key to log in is a disaster in my opinion. I brought mine into work today as I knew I'd need it but I assumed once I had logged in I would be remembered; I assumed worng, came back from lunch and I was logged out. There is no chance in hell I'll carry my security key around as the odds are that at some point I'll lose it. Same scenario applies to the Lodestone SE, not your brightest move.
