Configuring the **Maximum password age** policy setting to 0 so that users are never required to change their passwords is a major security risk because that allows a compromised password to be used by the malicious user for as long as the valid user is authorized access. +The longer a password exists, the higher the likelihood that it will be compromised by a brute force attack, by an attacker gaining general knowledge about the user, or by the user sharing the password.

For example, many organisations have compliance or insurance mandates requiring a short lifespan on passwords. Where such a requirement exists, the **Maximum password age** policy setting can be used to meet business requirements. ### Potential impact
