Step-by-step explanation:
The student asks about the percentage of people who keep written lists of their passwords. This question pertains to online security habits and practices which are part of the field of Computers and Technology. According to the information provided, while specific statistics about password keeping methods were not supplied, we know that 81 percent of people felt they had little control over data collected by companies, and 84 percent felt similarly about data collected by the government. This suggests a significant concern about online privacy and security among users.
The Pew Research Center reports show that a considerable number of individuals are worried about their personal information online, highlighting the importance of secure password management. While exact numbers on how many keep written lists are not given, these concerns likely prompt a certain percentage of people to keep written lists as a security measure, despite not being the most secure method. Individuals are encouraged to adopt stronger passwords, use two-factor authentication, and to educate themselves to avoid scams, indicating an industry move towards enhanced security measures.
