Abstract or Summary:
One method of ensuring secure passwords is to use system-assigned passwords. However, these tend to be random strings of characters that are difficult for users to remember. A promising alternative is the use of pronounceable passwords. Shay et al. have previously demonstrated that pronounceable passphrases show promise compared to random passwords. However, few researchers have examined pronounceable passwords in great depth.

In this preliminary work, we compare 3 non-pronounceable (heretofore called random) and 4 different pronounceable system-assigned passwords. We performed a 699 person, three part Mechanical Turk study to investigate the memorability and likability of these passwords. We explore two different non-pronounceable password generators: a slight modification of the existing Gasser algorithm and our own novel pronounceable password generator.
