In mid-May, the Administrative Office of the U.S. Courts (AO) began implementing multifactor authentication (MFA) to enhance system security for CM/ECF and PACER. MFA provides an added layer of security to accounts by helping protect against cyberattacks that steal passwords, significantly reducing the risk of unauthorized access.

All CM/ECF and PACER users are able to enroll in MFA. Users with filing and all other types of CM/ECF-level access are required to enroll in MFA, while users with PACER-only access have the option to enroll. By the end of 2025, everyone with CM/ECF-level access will be required to use MFA when logging in.

Additional information and updates are available on the PACER website.
