I feel the same way. Usually after I have given out the unlock code to my wife for one time use, I'll rotate it. My wife tells me the unlock code for her phone occasionally, and I never have bothered to commit it to memory. My toddler son watches me unlock the ipad for him, in a few weeks or so, he'll be able to unlock it himself.
