It is unfortunate that many organizations have instituted basic 4-digit codes to be used for a variety of security applications:
- bank and credit card pins
- luggage tags
- garage door opener
- home keyless locks
Almost everyone uses some form of their birthdate, combination of their birthdate (month, year), or other family members.
Interesting I read recently that the top ten 4 digit codes are:
It is estimated that the above 10 codes represent 15% of all user codes being used. Even worse is that once you know someone’s user code, they tend to use it everywhere, even for email accounts and computer passwords.
Certainly 4-digit codes have limited variations, but if you must use only 4-digits, please try and make the deterent a bit more difficult to overcome. Shake things up and use different codes in different places. And most of all, don’t be part of the 15%!
Are you guilty as well?
