Paul StarlingWhen its time to change your password the following rules should be observed:

  1. Don’t choose one obviously associated with youHackers can find out a lot about you from social media so if they are targeting you specifically and you choose, say, your pet’s name you’re in trouble.
  2. Choose words that don’t appear in a dictionaryHackers can pre-calculate the encrypted forms of whole dictionaries and easily reverse engineer your password. Use a two word phrase such ‘ComputerEngineer’
  3. Use a mixture of UYou can use a word or phrase that you can easily remember but where characters are substituted, eg, C@nturbury1
  4. Have different passwords for different sites and systemsIf hackers compromise one system you do not want them having the key to unlock all your other accounts.
  5. Keep them safeWith multiple passwords it is tempting to write them down and carry them around with you. Better to use some form of secure password vault on your phone.
