Yes, I am serious. We all have too many passwords to remember. A big security mistake is to use the same easy password everywhere. I recommend to my clients the use of ‘Pass Phrases’ or sentences. An example would be “Now is the time.” As a passphrase it would be typed out as ‘Nowisthetime.’
Pass phrases accomplish many tasks. Sentences are easier to remember than some long, cryptic password (i.e. 4M51jQ1). They meet the length and complexity requirements of most security systems. They are NOT your birthday, anniversary or kids/pets names. To change your password from site to site, add something to the end (i.e. Nowisthetime.ebay or Nowisthetime.yahoo).
It is good practice to change your passwords/passphrases every 3-6 months. Finally, please do NOT write your password down and stick it to your monitor or under your keyboard.
