Choosing Passwords

Passwords should be the maximum length allowed by the system.
Passwords should be hard to guess and should not contain:

• All the same numbers (for example, 1111, 666666)
  
  
• Sequential characters (for example, 123456)
  
  
• Numbers that can be associated with you or your business, such as your name, birthday, business name, business address, telephone number, or social security number
  
  
• Words and commonly used names

Passwords should be changed regularly--at least on a quarterly basis. Recycling old passwords is not recommended. Never program passwords (or authorization codes or barrier codes) onto a speed dial button.
