What is the function of an account expiration policy?

The function of an account expiration policy is primarily to boost account security during periods of inactivity. By implementing such a policy, organizations can prevent unauthorized access to accounts that have not been used for a specified period. When an account is set to expire, it becomes inactive, which mitigates the risk of potential breaches or misuse by individuals who may gain access to forgotten or abandoned accounts.

This security measure not only helps in protecting sensitive information but also enables administrators to keep their user account databases cleaner by identifying and managing dormant accounts effectively. While enhancing user experience or managing resources might be considered indirectly as benefits, the main focus of an account expiration policy is indeed on maintaining security by reducing opportunities for exploitation of inactive accounts.
