This paper describes two studies that looked at passwords for children. The first examined what children knew about the creation of textual passwords and then a second, follow on study, investigated the passwords that children chose to use. The two studies show that children have some understanding of how to make a good textual password but that the passwords they use are often in contradiction to their own knowledge of best practice. Based on the findings from these two studies, the authors propose three key design principles for systems that require textual passwords for children and where no alternative is available.
