      Hints to picking a great password

      These are two simple but great ways to help choose a strong password.

       

      1. Interlocking words
        • pick 2 words and interlock them. One word can be a current password, the second can be linked to the account or service the password is for.
        • e.g.
          • Base Password = iLoveCats (Cracked in 19 hours)
          • Account = TikTok (Cracked in 400ms)
          • New Password = iTLiokvTeoCkats (Cracked in 43 million years)
          • Benefits
            • Long password
            • 2 words you remember
            • Together they make a non-word (so password dictionaries wont work)
            • You can keep the same base password but have a new password for each account.
          • Even better if
            • numbers and special characters added
      2. Memorable phrases
        • Think of an easy to remember phrase then add numbers and special characters to replace letters
        • e.g.
          • Phrase = Get hacking or get hacked
          • With numbers and special characters = g3tH4ck1n90r93th&ck3d (cracked in 3 sextillion years)
