Starting mid-May, the Administrative Office of the U.S. Courts (AO) will begin 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.

Once implemented, all CM/ECF and PACER users will be able to enroll in MFA. Enrollment for users with CM/ECF-level access is mandatory, while users with PACER-only access will have the option to enroll.  

Users with CM/ECF-level access who do not voluntarily enroll will be randomly selected to enroll beginning later this month and throughout the rest of the year. By the end of 2025, everyone with CM/ECF-level access will be required to use MFA when logging in.

More information about the MFA process is available on the PACER website.
