• Create an acronym from an easy-to-remember piece of information. For example, pick a phrase that is meaningful to you, such as My son's birthday is 12 December, 2004. Using that phrase as your guide, you might use Msbi12/Dec,4 for your password.



• Substitute numbers, symbols, and misspellings for letters or words in an easy-to-remember phrase. For example, My son's birthday is 12 December, 2004 could become Mi$un's Brthd8iz 12124 (it's OK to use spaces in your password).

• Relate your password to a favourite hobby or sport. For example, ‘I love to play badminton’ could become ILuv2PlayB@dm1nt()n.



Highly Recommended

• Use secure, unique passwords for every Internet site or service is one of the best security practices out there.

• Use a single master password for storage of all passwords, then never user it again!
