1. Security and user experience (UX) are often seen as competing priorities, but they should be considered together from the beginning of the design process. A system is both secure and usable when it behaves as the user expects whether facing human errors, technical issues, or malicious attacks.
2. Passwords are a common source of security and usability issues. Users often choose weak, predictable passwords because strong passwords are difficult to remember and enter.
3. Even small design flaws can undermine security if they create unexpected behaviors that are exploited by attackers. Designing with both security and usability in mind from the start is important to avoid vulnerabilities.
