Password Requirements and Complexity

Leidos enforces certain requirements and complexity on passwords to reduce threats against easy passwords.

Make sure your passwords are as follows:

  • Must be a minimum of 12 characters
  • Must contain at least 3 of the 4 character types:
    • Lower case alphabetic letters (a-z)
    • UPPER case alphabetic letters (A-Z)
    • Numeric (0-9)
    • Special characters (such as: *&^%$#@!)
  • Must be different from the last 13 passwords
  • Must not be a variation of your name or username
  • Spaces are accepted

Tips on Developing a Complex Password

  • Avoid using common knowledge facts about you, such as what car you drive, what your house color is, your favorite number, pet names, birth date, etc.
  • Using spaces in the middle of your password can increase the complexity of your password.
  • Use uncommon special characters, such as [ ] { } ; : ` "
  • Using a passphrase can be easier to remember than a phrase association.
  • Avoid using one password for everything. If your password is compromised, the adversary would be able to log into many of the other services.

How to Utilize Complex Passwords

Passphrases can take longer to crack than a phrase association. A passphrase is using an entire phrase where a phrase association takes the phrase and creates an acronym-like string.

Here is an example of how a passphrase can be more effective than a phrase association:

Passphrase: June 18 is Aunt Betty's 50th Birthday!
This can take up to 4.58 thousand trillion trillion trillion trillion centuries to crack - that's a really long time!

Phrase Association: 0618=AB50Bdy!
This would likely take less than half the amount of time to crack than the passphrase referenced above.
