What factors can affect the strength of a password?

The strength of a password is influenced by multiple factors, making option C correct. When creating a secure password, it is essential to consider several components:

1. Length: Longer passwords are typically more secure, as the number of possible combinations increases exponentially with each additional character. A password that is at least 12 to 16 characters is generally recommended for robust security.

2. Case Sensitivity: Using both uppercase and lowercase letters adds complexity to a password. This increases the number of potential combinations, diminishing the likelihood of a successful brute-force attack.

3. Numerical Characters: Including numbers in your password provides more variation, further enhancing its strength. It increases the complexity as the possible characters shift from 26 (if using only letters) to 36 or more.

4. Special Characters: Incorporating special characters (such as @, #, $, %, etc.) adds another layer of complexity, as these characters expand the password character set beyond alphanumeric options.

All these factors combined lead to a significantly stronger password that is harder for attackers to guess or crack through various methods such as brute force attacks, dictionary attacks, or using stolen password databases. This holistic approach to password creation is vital for maintaining security in
