Why are complex passwords recommended?

Complex passwords are recommended primarily to enhance security and hinder unauthorized access. A complex password typically includes a mix of uppercase and lowercase letters, numbers, and special characters. This combination significantly increases the number of potential password combinations, making it much more difficult for attackers to guess or crack the password using brute force methods or dictionary attacks.

Furthermore, complex passwords help protect against various types of attacks such as social engineering and credential-stuffing, where attackers use stolen password lists to access multiple accounts. By utilizing passwords that are harder to predict or guess, organizations and individuals can protect sensitive information and systems from unauthorized access, reducing the risk of data breaches and cyber incidents.

While compliance with software licenses, reduction in memory usage, and simplification of account recovery may be relevant in various contexts, they do not directly address the primary purpose and importance of using complex passwords in enhancing overall security.
