Being the "techy" kid in a 7 person family meant I was responsible for setting up any new devices on our wifi many many years ago. From the number of phones/consoles/laptops set up on the same WEP key, I have the 26 digit random hex string permanently ingrained in my memory. While I don't use it as a password any more, before password managers I'm pretty sure I had one of if not _the_ most secure banking password at the time.
