It was recently reported in a posting on that as of 2016 the five top most commonly used passwords on the Internet and therefore the worst to use from a security standpoint are:


  1. 123456
  2. password
  3. 12345
  4. 123456789
  5. qwerty

Unfortunately people are still using these passwords because they are easy to remember. Some industry experts recommend using no fewer than 9 characters, with at least one number, a symbol and an upper case character and no sequential patterns. The thought is that 6 characters takes possibly seconds to break, but 9 or more non-sequenced characters makes it more difficult so hackers may move on. Changing your passwords regularly is also key. Some cyber security measures start with the simplest of items, strong passwords being one of them.
