A password is

A password is

• A. Always secure
• B. Always memorable
• C. Frequently used
• D. Easy to guess

Answer: (C)

Passwords are a common method of authentication, but they’re not inherently secure. The statement that a password is frequently used captures the practical reality: people rely on passwords across many sites and services, and they often reuse or choose weak ones. This widespread usage creates vulnerabilities that security measures must address, such as enforcing strong length and complexity and supporting multi-factor authentication. The other descriptions aren’t reliable across real-world usage—passwords aren’t always secure, they aren’t always memorable (strong passwords tend to be hard to remember), and while some passwords are easy to guess, not all are.
