Since the DOD has made the password requirement impossible, I’ve been coming up with complex password methods that are easy to remember.
Here is one:
Passwords based on three digit primes on small areas of the keyboard.
135 – prime three digits
!#% – special characters of the prime
QET – cap letters under the prime (to left)
wrr – lower letters under the prime (right)
You choose a row of prime numbers. Then you base all the other digits on that prime.
