Which of the following is a bad practice for identity theft prevention?

The practice of using a single password for all accounts is considered a bad practice for identity theft prevention because it significantly increases vulnerability. When one password is compromised, all accounts using that same password are at risk, creating a domino effect that could lead to widespread access to sensitive information and accounts.

Good security practices emphasize the importance of unique, complex passwords for different accounts. This way, even if one account is breached, the others remain protected, thereby mitigating the potential damage.

In contrast, practices such as using biometric authentication, suspending mail during vacations, and installing antivirus software are all proactive measures that enhance security. Biometric authentication adds an extra layer of identity verification that is difficult for an identity thief to replicate. Suspending mail helps prevent sensitive personal information from being intercepted while one is away. Installing antivirus software safeguards against malicious software that could compromise personal data. Collectively, these practices demonstrate diligence in protecting against identity theft.
