Users are susceptible to password guessing attacks when they create weak passwords. Despite an abundance of text-based password advice, it appears insufficient to help home users create strong memorable passwords. The authors propose that users would be empowered to make better password choices if they understood how password guessing attacks work through visual communication. They created three infographic posters and an online educational comic to help users to learn about the threats. They conducted two studies to assess their effectiveness. All four methods led to superior learning outcomes than the textalone approach. Their pre-test questionnaires also highlighted that users' understanding of password guessing attacks is limited to a \"Target\" mental model.
