I thought I had a full proof password once. It was given to me by some bureaucratic system that generated it. Out of desperation I memorized it and used it everywhere. Mostly a bunch of nonsense letters, numbers and symbols.
But recently a system rejected it when I tried to use it because I guess two of the numbers in it are sequential? Also there were 2 repeating numbers, which wasn’t allowed anymore I guess. Not to mention I had at least one upper case and one lower case letter that were the same letter! All my capitalized letters were not allowed to appear later as lowercase letters layer in the password?
For crying out loud!
