There are four characteristics that strong passwords have: length, complexity, variation, and variety. The password must be at least more than eight characters. It must be complex, using the entire keyboard. It should have capitalization, numbers, and symbols—the more intricate the better. Some hacking software even check for easy replacement of letters to symbols; for example: & versus and; 2 versus two, etc. Therefore, avoid letter-to-symbols adaptations. However, no matter how strong the password is, it can still be hacked. Thus, users should take care to change the passwords of important accounts every 3 months. Lastly, a variety of different passwords should be applied to different accounts. The same password for multiple accounts is a big no-no.
There are
many services out there that can help with creating passwords. Some password
management softwares have their own password creator. If remembering too many passwords
is a chore, consider a password management software. Avoid writing down
passwords because it may be lost or stolen. Moreover, common errors when
creating passwords are using sequence or repeated characters, personal
information (birthdates, name, license, and other important numbers), and
common words.
