What is the main focus of the "Minimum password age" policy?

The "Minimum password age" policy is primarily concerned with limiting how frequently users can change their passwords. By setting a minimum password age, organizations can prevent users from changing their passwords multiple times in a short period to bypass password history requirements. This is important for maintaining the integrity of password policies and encouraging users to adopt and retain strong passwords for a longer duration.

The idea behind this policy is to strike a balance between user convenience and security. Allowing users to change passwords too frequently can enable them to quickly revert to a previously used password that may not be secure, especially if a password is weak. Therefore, enforcing a minimum duration before a password can be changed helps to enhance overall security by compelling users to remain with a given password longer and, ideally, ensure that they are creating more complex and secure passwords when they do change them.

While other policies focus on aspects like password strength, expiration dates, or maintaining a history of used passwords, the minimum password age specifically deals with the frequency of changes, underlining its primary focus in managing password practices effectively.
