Mrs Sugden knew a thing or two about the power of changing hair colour. But she may not have realised its part in cyber-security.
A strong password should have a minimum password length of 12 to 14 characters, include lowercase and uppercase alphabetic characters, numbers and symbols and be randomly generated. However, this makes for a password that is very difficult to remember.
As an alternative, passphrases or passphrase derived passwords are easy to remember, whilst remaining difficult to crack. The phrase
My grandmother Ethel paid £39 for a blue rinse!
Becomes the passphrase MygrandmotherEthelpaid£39forabluerinse! or if this is too long, the password MgEp£39fabr! using the first letters of each word.
When you need to change the password, change a word in the passphrase:
My grandmother Ethel paid £39 for a pink rinse!
My uncle Bert paid £39 for a blue rinse!
My grandmother Ethel paid £32 for a blue rinse!
The more interesting you make the phrase, the easier it is to remember.
