At IU, how can I choose a secure PIN?
Several Indiana University services require the use of PINs (personal identification numbers). When creating or changing a PIN, it is important to use the same care you would in choosing a password or passphrase. Some general guidelines for creating a PIN are:
- Do not use birthdates, anniversaries, or similar numbers as your
PIN. An unauthorized user can often easily find this information
via social networking sites or an Internet search.
- If the PIN allows alphabetic characters, use a mix of letters
- Do not use an actual word or name as your PIN; similarly, do not
use a word misspelled with a number/letter substitution (e.g.,
- Do not use the PIN that you use for your personal banking, or
that is a password on another site.
- Treat your PIN as you would any other password: use one that you can remember without writing down; do not share your PIN with anyone; and change it if you believe it may have been compromised.
