i dont find it irritating at all, it am in fact pleased that they are trying to produce a system to protect our stuff.

Its only irritating because we play multiple accounts, its something we have to deal with, we are the exception to the casual gamer and they dont build things to suit our needs.

I have only had to input my codes 5 times only once, if you are having to do it each time you log in then there are other issues.
