PACER Multifactor Authentication (MFA) Requirement
PACER recently deployed a multifactor authentication requirement. The Court is not involved in that process and PACER is an independent system. The Court understands, however, that the members of the bar of the Court are impacted by this change and many have experienced challenges with enrolling in the new system. The following is a brief tutorial on how to enroll in multifactor authentication.
You will receive a pop-up notification of the requirement to enroll in MFA when you log in to PACER (see screenshot below). You will not be sent an email regarding this requirement.

You get three chances to skip setting up. Prior to enrolling in MFA, you should confirm that the email address associated with your PACER account is correct and accessible. You can check and update your email address in Manage My Account under the Settings tab.
Refer to the Learning Aids on PACER website.
You may use your cellphone, desktop, web, or browser-based authentication applications (apps) or tools (e.g., web apps, browser extensions, and desktop apps) that support time-based, one-time password (TOTP).
The federal judiciary does not endorse specific authentication apps; however, some options include Authy, DUO Mobile, FreeOTP, Google Authenticator, and Microsoft Authenticator.
When setting up the Authenticator app a security code will be sent to the email address on file in your Pacer account. Check your email box, copy and paste the code information into the security code screen on your computer.

Follow the prompts to continue setting up App. See Learning Aids - Steps 7 - 10.
Check junk/spam folders.
Click "Get New Codes" on Multifactor Authentication Methods screen. You will be sent a one-time security code to your email address on file in your Pacer account. Check your email box, copy and paste the code information into the security code screen on your computer and click submit.
