Starting mid-May, the Administrative Office of the U.S. Court (AO) will begin implementing multifactor authentication (MFA) to enhance system security for PACER and CM/ECF. MFA provides an added layer of security to accounts by helping to protect against cyberattacks and other security risks, significantly reducing the risk of unauthorized access.

Once implemented, all CM/ECF and PACER users will be able to enroll in MFA.

Users with any type of CM/ECF-level access will be required to enroll in MFA. Those who do not voluntarily enroll will be randomly selected to enroll and will be notified of the MFA requirement at login. By the end of 2025, all users with CM/ECF-level access will be required to use MFA.

Users with PACER-only accounts that do not have filing privileges in any court will have the option to enroll.
