Multi-Factor Authentication Assistance

Information for Applicants

New Applicants -- eApp users logging in to complete their standard forms will use an authentication application to access the system.

  • Users will receive an invitation email from NBIS (noreply@nbis.mil).

    • Subject line will read - *ACTION REQUIRED* Activate Your New NBIS eApp Account.

Key Information for Accessing Your eApp Application:

  • Use Your Provided Username: The only way to access your eApp for a background check is to use the username provided in the "*ACTION REQUIRED* Activate Your New NBIS eApp Account" email. 
  • PIV/CAC Login is Not Supported: Please be aware that Personal Identity Verification (PIV) or Common Access Card (CAC) login will not provide access to your eApp application. Using these methods will result in an error.
What to Do If You've Forgotten Your Password:
If you've lost or forgotten your password, resetting it is simple:

  • Go to the main eApp login page.

  • Enter your username in the designated field.

  • Follow the prompts to reset your password. A password reset link will be sent to the email address associated with your account.

Existing applicants – Existing eApp applicants will be prompted to change their password upon login. After changing your password, please follow the steps below: 

  • Choose Authentication Method: Click 'Continue' to set up your preferred method for receiving one-time passcodes (OTPs). You'll use these OTPs to verify your identity each time you log in. While email is an option, we highly recommend using an authenticator app for improved security. 

  • Launch eApp: After entering the portal, select the 'eApp' tile to launch the application.  

  • Verify Identity: For security purposes, the first time you use eApp, you'll be asked to verify your identity with your Social Security number (SSN) and Date of Birth (DOB).
