Better login/out format

I think its about time that EA add a proper log in and out section the are where link accounts isn't sufficient enough, I have just experienced something where due to a glitch on the redeem.ea site my fcmobile account  that was linked to my email got link another fcmobile account so now I can redeem codes unless I delete someones account which isn't fair.So EA pls develop o PROPER log in and out section we can use.
