How frequently are users required to change their passwords?

The requirement for users to change their passwords is outlined in the PCI DSS, which emphasizes the importance of maintaining strong security practices to safeguard cardholder data. Setting an interval for password changes is a measure to reduce the risk of unauthorized access stemming from compromised password credentials.

In the context of this question, changing passwords every 90 days aligns with the PCI DSS recommendation, emphasizing the need for organizations to implement password policies that mitigate risks associated with long-term exposure of potentially compromised passwords. This timeframe allows for a balance between security and usability, ensuring that users remain vigilant about password management without causing excessive inconvenience.

Adhering to a 90-day password change policy helps organizations maintain compliance with security standards designed to protect sensitive information while promoting a culture of proactive security measures among employees and users.
