Answer :
Final answer:
Password complexity and the use of multi-factor authentication are essential for securing accounts against unauthorized access. The best practices include using long and complex passwords, not reusing them across different sites, and enabling multi-factor authentication for an additional layer of security. Therefore correct option E) I use multi-factor authentication, and it enhances security.
Explanation:
The subject of this question pertains to password management and the use of multi-factor authentication (MFA), which are critical components of cybersecurity in accounts security. Passwords play a crucial role in protecting personal and work accounts, and their complexity is a significant factor. It is recommended that passwords should be long, with a mix of uppercase and lowercase letters, numbers, and special characters to prevent brute-force or dictionary attacks.
MFA enhances account security by adding an additional layer of authentication beyond just the password. For instance, in addition to a password, you might also need to input a code sent to your phone or use a biometric factor like a fingerprint. This makes it considerably harder for adversaries to access your accounts as they would need both your password and access to your secondary authentication method.
As best practices, do not reuse passwords across multiple sites. Use a password manager to create and store complex passwords, and always opt for MFA wherever possible, especially on critical accounts like email, banking, or work systems, to significantly reduce the risk of unauthorized access.
