Recently United Airlines notified both my husband Olof and me that we would have to strengthen our passwords on our mileage accounts and select new security questions. Olof and I hate security questions. For virtually all of our accounts – financial, travel, etc. – we try to use a single account so we can have security questions that we would both know the answer to. City where we were married (La Jolla) is always a good choice, although this is actually both of our second marriages, so even that one has potential for confusion. We always go for Olof’s first pet. City where you were born has at least a 50 percent chance of being correct. We never use grandmother’s maiden name since neither of us can remember our own much less the other person’s.
