A.4.1.2. Complex passwords
Strong passwords are an important protection that helps to configure safe environments. The following
requirements define a strong password and are adapted from a Microsoft article about strong passwords:
▪ Password length: Make sure that the password consists of at least 8 characters
▪ Password complexity: Include letters, punctuations, symbols and numbers
▪ Password variation: Change the password often
▪ Password variety: Do not use the same password for everything
There are many ways to create a strong password. The following table shows some suggestions that might
help you to remember a password easily:
What to do Example
Start with a sentence or two Complex passwords are safer
Remove the spaces between the words Complexpasswordsaresafer
Turn words into shorthand or intensionally misspell a
word ComplekspasswordsRsafer
Add length with numbers and symbols ComplekspasswordsRsafer#2013#
Keep in mind: Cyber criminals use sophisticated tools that can rapidly decipher passwords. Avoid creating
passwords that use:
▪ Dictionary words in any language
▪ Words spelled backwards, common misspellings and abbreviations
▪ Sequences or repeated characters, e.g. 12345678 or abcdefgh
▪ Personal information, e.g. birthday or passport number
