In mid-May, the Federal Judiciary will begin implementing multifactor authentication (MFA) to enhance system security for CM/ECF and PACER.

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

From mid-May to the end of 2025, users who do not voluntarily enroll will be randomly selected to do so during login. By the end of 2025, everyone with CM/ECF-level access will be required to use MFA when logging in. For more information, see the announcement posted on PACER.gov https://pacer.uscourts.gov/announcements/2025/04/04/multifactor-authentication-coming-soon
