On May 11, 2025, the Administrative Office of the U.S. Courts (AO) will begin implementing Multifactor Authentication (MFA) to enhance system security for Case Management/Electronic Case Files (CM/ECF) and Public Access to Court Electronic Records (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.

Electronic filers with any type of CM/ECF-level access who do not voluntarily enroll will be randomly selected to do so. These randomly selected CM/ECF users will be notified of the MFA requirement during login. By the end of 2025, everyone with CM/ECF-level access will be required to use MFA when logging in.

Electronic filers with PACER-only access accounts will not be required to have MFA enabled, but will have the option to enroll. All other accounts that can file in CM/ECF will be required to enroll.

The announcement from PACER provides additional details about the upcoming MFA changes.
