Password Poems

Study by Ghazvininejad & Knight, 2015 – Univ. of Southern California

http://www.isi.edu/natural-language/mt/memorize-random-60.pdf

Long human history of oral storytelling and poems. Rhyming poetry has long been used by humans to increase memorability.

The researchers found that by creating a short rhyming poem of random words, a very secure (difficult to hack) yet easy to remember password could be created.

Their formula employs a rhyming iambic tetrameter couplet format, with two lines with eight syllables each, ending with rhyming words.

Sample password generator (do not use any of these!!): http://www.isi.edu/natural-language/people/poem/poem.php

An example from the above site:

Discarding rafters substitutes

campaigns Miami prostitutes

A truly random (and safe) password can be generated here: http://52.24.230.241/bc/password_generation.php

 

Password Phrases

 

Think of a phrase you will always remember

“A fool and his money are soon parted.”

Take the first letter of each word.

afahmasp

Add some capital letters.

AfahMasp

Add some special characters & numbers.

Afah%Masp38

Voila! Easy to remember and just as hard to crack as a randomly generated sequence of characters.
