What action updates factory-set passwords to enhance security?

• A. Changing the default password
• B. Resetting the device to factory default
• C. Disabling password protection
• D. Storing credentials in plain text

Answer: (A)

Default credentials present a common security gap. The action that updates factory-set passwords is changing the default password. By replacing the manufacturer’s preset login with a unique, strong password, you prevent attackers who know the default from gaining easy access and you ensure the device is only accessible by someone who knows the new secret. This simple step is a foundational security practice during initial setup. Restoring factory defaults would bring back the original credentials, reintroducing the risk. Turning off password protection removes authentication altogether, making access trivial. Storing credentials in plain text is insecure because anyone who can read the storage could reveal them, defeating the purpose of the password.
