Improved passphrases could make online experiences both user-friendly and secure

Although passphrases, or phrase-based passwords, have been found to be more secure than traditional passwords, human factors issues such as typographical errors and memorability have slowed their wider adoption. Kevin Juang and Joel Greenstein, in their recently published Human Factors article, "Integrating Visual Mnemonics and Input Feedback With Passphrases to Improve the Usability and Security of Digital Authentication," developed and tested two new passphrase systems that seek to address these shortcomings and improve the usability and security of existing passphrase authentication systems.
The authors'' first passphrase system incorporated, in part, a specialized wordlist using simple, common words; a six-word sentence structure that made meaningful sense; and a user-created mnemonic picture to assist with recall. The final result would be a passphrase such as "silly pet wolf ate our pizzas," with an accompanying user-generated illustration. The second passphrase system replaced the six-word sentence structure with four words randomly drawn from a customized 1,450-word list.
