Before You Start

Make sure you have the following ready:

  • Your contract vehicle name (example: ASTRO, OASIS+)
  • MFA Readiness: You will need an Authenticator App or a cell phone for Multi-Factor Authentication (MFA) setup.


Steps

1. Identify Your Contract Vehicle

Because some sites do not have a special logo (like Polaris) or use a shared agency logo (like DHA), always check the website address (URL) at the top of your browser to make sure you are in the right place. Symphony supports the following contract vehicles:

2. Confirm Your Contract Vehicle Portal

Once you have identified the contract vehicle for your solicitation or award: 

  1. Navigate to the Symphony website tied to that contract vehicle.
  2. Verify the URL (on the Address Bar) and agency logo on the sign-in page.
  3. Stop if the URL or logo does not match your contract vehicle.
Warning: Using the wrong website will cause an authentication failed error.

3. Register, Sign In, and Activate

Once you are on the correct contract vehicle website, you can either register or sign in to your account. 

To Register Your Account

  1. Click Register Now after accepting the Official Use notice.
  2. Complete the registration process based on your organizational role.
  3. Set up a preferred method of Multi-Factor Authentication (MFA). 
  4. After you register, your administrator must approve your account before activation. 


Sign in to Your Account

  1. Open the Symphony website for your contract vehicle.
  2. Confirm the portal is correct by checking the URL (on the Address Bar) or agency logo on the sign-in screen.
  3. Enter your email address and password.
  4. Select Sign In.
Note: If you see Account Inactive, your administrator must approve your account before activation. See Manage Your Symphony Sign-In and Account Activation for more information.


4. Use MFA Correctly Across Contract Vehicles

Each Symphony website needs its own MFA setup.

  • Setup: Complete the MFA step for every contract vehicle you use.
  • Rename: The default name is always SymphonyPS. Rename the codes in your authenticator app so you know which one belongs to each site (for example: OASIS+ or ASTRO).
  • Unique Codes: Use the specific code for the website you are visiting. Codes for one site will not work on another.

  

5. Understand Contract Vehicle Data Boundaries

Your access and assets are separated by contract vehicle and organization identifiers. You cannot share company assets across different UEIs/CAGE codes or contract vehicles.


Troubleshooting

IssueFix
Authentication Failed after entering your password.Check Your Portal: You are likely on the wrong contract vehicle website. Verify the URL and the Agency Logo on the sign-in page before trying again.
MFA code is not working.Portal Mismatch: The code may be for a different Symphony website. Ensure you are using the code specifically labeled for the URL you are currently visiting. See the Set Up and Use Multi-Factor Authentication (MFA) guide for troubleshooting, or Submit a Ticket to the Symphony Help Desk (for lockouts).
I cannot find my contracts or company assets.Check Data Boundaries: Verify you registered on the correct URL and that your UEI and CAGE code are correct. Data is isolated by contract vehicle and cannot be transferred or viewed across different portals.
