How to Invent a Password, from the folks at UPenn

Inventing a password

Make up a sentence that’s meaningful to you. Then use the first letter of each word as a letter in your password; if you wish, add additional characters to make it more difficult to guess.

  • Start with the phrase such as Orange elephants invade Alaska; film at eleven.
  • Take the first letter of each word as your password: OeiAfae (This is an acceptable password; it follows the rules but is hard for someone to guess since it’s essentially a random string of characters.)
  • To make the password even harder to guess, add punctuation, numbers, and other non-alphanumeric symbols: OeiA;f@11

Users should expect that the password selection rules will get still more strict over the course of time.
