Which practice is not recommended for personal identity theft prevention?

• A. Use the same password or passphrase for all accounts
• B. Use biometric authentication when available
• C. Instruct the post office to suspend mail during vacations
• D. Avoid using unsecured, public Wi-Fi networks

Answer: (A)

The main idea here is that reusing the same password across multiple accounts creates a single point of failure. If one site is breached and your password is exposed, the attacker can try that same password on your other accounts, potentially gaining access to a lot of sensitive information. That’s why using unique, strong passwords for every account is essential, and why a password manager helps you keep them straight. Adding multi-factor authentication where available adds an extra layer of protection beyond just the password. The other practices reinforce security: biometric authentication relies on something you are, which can be harder for attackers to spoof; suspending mail during vacations helps prevent theft of physical mail containing sensitive information; and avoiding unsecured public Wi‑Fi reduces the risk of data being intercepted when you’re online.
