On May 11, 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. Users with filing and all other types of CM/ECF-level access will be required to enroll in MFA, while users with PACER-only access will have the option to enroll.  

Users with filing privileges and other types of CM/ECF-level access are encouraged to enroll in MFA at their earliest convenience to preserve uninterrupted access.  Those who do not voluntarily enroll in MFA will be randomly selected to enroll starting in August 2025. Documentation and learning aids are available on the PACER website. 

Questions? Contact the PACER Service Center at pacer@psc.uscourts.gov or (800) 676-6856. The PACER Service Center hours of operation are Monday through Friday 8 a.m. to 6 p.m. CT.
