A password can encompass all of the criteria indicated in our previous publication and still be unsafe. For instance, “Hello2U!” meets all of the criteria mentioned for a safe password, but is unsafe because it has a full word. “H3ll0 2 U!” is a safer alternative because it replaces some letters in the full word with numbers and includes spaces.
You can apply the following recommendations to build a safe password:
Create an acronym with information that will be easy to remember. For example, choose a phrase that has a meaning to you, such as “My son was born on December 2004”. Using that phrase as guide, you can use “MswboDec/12,4” as a password.
Use numbers, symbols and orthography errors to replace letters or words in an easy-to-remember phrase. For instance, “My son was born on December 2004” could become “M’sn wb@rn 12124” (you can use spaces in a password).
Relate your password to a hobby or favorite sport. For example, “I love badminton” can become “I’lvB@dm1nt()n”.
If you think you need to write the password down in order to remember it, remember not to write that it is your password, and keep it in a safe place.
