Re: President Password
The passwords described would not have worked in the US DoD in 2005 or 6, possibly earlier. The standards when I retired at the end of 2011 were length of 12, at least two each of upper case, lower case, digits, and special characters (subject to acceptance by the application or system). New passwords were to be different from any of the last 10, from any used less than a year in the past, and from the password used on any other system. Three consecutive occurrences of the same character were never allowed, and some systems disallowed all repeats, ascending or descending digit sequences, or both. Password change was required every 60 days or less and most systems and applications enforced that.
Some of the properties, of course, could not be validated automatically, and some systems and applications enforced standards better than others. Password managers were gaining popularity, but spreadsheets or notes in drawers were more or less the norm.
