COVID-19 News, Innovations and Insights.

Children are increasingly being exposed to and using, technology from a very young age. This has never been more true than in 2020 when the vast majority of children worldwide have used online resources to access educational resources and communicate with family and friends during the COVID-19 pandemic.

Many of the resources and websites used, along with the devices they are accessed on, require the use of a password to authenticate the user. However, young children don’t necessarily have the skills and knowledge required to use and maintain these passwords appropriately. They are likely to use weak, predictable passwords and tell other children their passwords.

Children come from a variety of different backgrounds and their parents will have a wide range of cyber-related skills. They might pick up some password related knowledge but there is no guarantee that they will learn the correct principles.

This situation led us to wonder what principles children should learn, and when they should learn them. To answer this question, we carried out research to:

  1. Determine what current best practice is with respect to password management, gathering the information from international standards bodies. We wanted to gather a set of password “best practice” principles.
  2. Gauge the best age at which to introduce each “best practice” principle by consulting the child development literature.
  3. Develop three sets of age-appropriate password “best practice” principles, to ensure that children learn the correct principles as and when they are ready for them.

Organisations have tended to advise that passwords should be at least eight alphanumeric characters long, contain digits or punctuation characters as well as letters, and both upper and lower case characters.

This essentially imposes complexity requirements on passwords. But in 2017, the National Institute for Standards and Technology, the UK’s National Cyber Security Centre and the Centre for Protection of National Infrastructure published revised password guidelines. One important change is that length, not complexity, characterises strong passwords. Other widespread practices have also been replaced. For example, they advise against automatically replacing passwords at regular intervals.

So, we worked through these reports and derived a set of password “best practice” principles.

The next step was to investigate the child development literature, to provide a baseline for creating three sets of appropriate “best practice” principles. A number of relevant developmental aspects emerged: emerging literacy, ability to focus, and the ability to discriminate between people they can tell secrets to, and those they shouldn’t.

There are also issues for children with dyslexia. These children experience difficulties in learning to read and to parse words into individual characters. This makes password usage challenging.

Best practice
Based on these insights, we allocated the principles to three different sets, for children aged 4-5, 6-7 and 8-9. These ensure that the principles will be taught when children are ready to learn and apply them.

We then ran focus groups with parents of children of these ages, to ensure that we had assigned appropriate principles to each age group. We also rephrased the principles to make them child friendly. For example, instead of naming “impersonation” as being a consequence of password leakage, we rephrased that to: “someone telling the computer that they are you”.

Our next project aims to test these initial sets of principles by giving them to teachers and parents to help them to educate the children in their care. We hope to refine them based on their feedback.
