USAfx: Secure File Exchange for DOJ & Legal Partners – Login & Features

Quick Summary

  • DOJ's secure file sharing platform
  • Invitation-based access
  • Multi-factor authentication required
  • Temporary data exchange, not storage
  • Built on Box.com technology

The USA File Exchange, known as USAfx, is a secure digital portal specifically designed by the Department of Justice's Executive Office for U.S. Attorneys (EOUSA). This platform facilitates the secure exchange of electronically stored information (ESI) between the U.S. Attorney's Office and external entities, such as private law firms and other legal partners. It serves as a critical component for managing case materials, including eDiscovery documents, by providing a controlled and encrypted environment for data transfer. USAfx is built upon the Box Enterprise Cloud Content Collaboration Platform, leveraging its robust infrastructure to ensure that sensitive information is handled with the utmost care. Unlike a permanent storage system, USAfx is intended for the short-term transfer of data for official business purposes, making it an essential tool for legal proceedings.

Core Capabilities of the USAfx File Exchange

Resolving Common Access Challenges with USAfx

⚠️ Unable to Log In or Password Reset Issues

Cause: Users often report not receiving password reset emails or being locked out. This can happen if the temporary password expired, the account wasn't fully registered, or a system administrator reset is required.

Solution: If you are unable to access your USAfx account or are not receiving password reset emails, you might need administrator assistance. We know being locked out is stressful. The fastest fix is often to contact the specific U.S. Attorney's Office that sponsored your account or their designated USAfx team directly, as they may need to initiate a password reset for you.

⚠️ Authentication Phone Number is No Longer Available

Cause: The phone number registered for multi-factor authentication may have changed or belongs to a former team member, preventing successful login.

Solution: If your authentication phone number is outdated or unavailable, you will need to contact the USAfx team of the U.S. Attorney's Office that sponsored your account. They can update your contact information and reset your MFA settings, allowing you to regain access.

⚠️ Shared File or Folder Link is Unavailable

Cause: A shared link might have been removed, or access to the specific folder has been revoked or expired. USAfx files have a short-term retention policy.

Solution: If you encounter a message stating a shared file or folder link is unavailable, reach out to the sender or the folder owner. They can verify if the folder is still active, if your access permissions are correct, or if the content has passed its retention period and been removed from the system.

Q: Why am I not receiving the USAfx password reset email?

If you are not receiving USAfx password reset emails, it's possible the email is going to your spam folder, or there may be an issue requiring administrator intervention. You should contact the USAfx team of the sponsoring U.S. Attorney's Office for assistance with a manual password reset.

Q: What is the USAfx website address?

The official website address for the USAfx portal is usafx.justice.gov.
