What characterizes a strong password policy?

A strong password policy is characterized by specific requirements that enhance security and reduce the risk of unauthorized access. One critical aspect of a robust password policy is the requirement for passwords to be of sufficient length and complexity. Requiring a minimum of 12 characters with complexity means that the password must not only be longer but also include a mix of uppercase letters, lowercase letters, numbers, and special characters. This combination makes it significantly harder for attackers to guess or crack passwords through brute-force attacks or dictionary attacks.

Longer passwords provide a more extensive set of combinations, exponentially increasing the time required for an attacker to generate all possible passwords. Additionally, complexity requirements prevent the use of common words or easily guessable sequences, further enhancing security.

In contrast, shorter passwords or those based on easily accessible personal information do not provide adequate protection against modern attack methods. Allowing password reuse also poses risks, as it can lead to a situation where compromised passwords across multiple accounts make it easy for attackers to gain unauthorized access. Thus, the requirement for longer, complex passwords is central to creating a strong password policy.
