What is considered a strong password policy?

A strong password policy is characterized by its emphasis on complexity and regular updates, which significantly enhance security. Requiring complex passwords means that the passwords should include a mix of uppercase and lowercase letters, numbers, and special characters. This diversity makes it much harder for attackers to guess or crack the passwords through brute force methods.

Regularly updating passwords ensures that even if a password is compromised, its validity is temporary, thus further protecting sensitive information. The combination of these practices aligns with best security standards, reducing the risk of unauthorized access to systems and data.

Other approaches mentioned, such as allowing short and simple passwords or requiring users to write passwords down, significantly weaken security. Short passwords can be easier to guess, while writing them down creates physical vulnerabilities. Additionally, the statement about using public Wi-Fi for access could expose users to significant security risks, as public networks often lack encryption and can be easily exploited by malicious actors.
