PINs must be between 9 and at most 64 characters long.
PINs may not contain your user name or any part of your full name.
PINs must contain characters from the following 4 character sets:
1. Upper case letters (i.e. A, B, C, etc.)
2. Lower case letters (i.e. x, y, z, etc.)
3. Numbers (i.e. 0, 1, 2, etc.)
4. Non-alphanumeric or “special” characters (i.e. @, &, *, etc.)
PINs automatically expire every six months and you will be required to choose a new PIN at that time. You may not reuse your last five PINs.
Don't use familiar names or dictionary words; instead combine misspelled words, use passphrases and create keyboard pattern PINs.
Once you've picked a strong PIN, handle it appropriately. Don't write it down. If you absolutely must write it down, keep it in a safe or a locked drawer - and definitely not on the yellow sticky note on the side of your screen.
