Setup Two-Factor Authentication

Why it's required

When accessing GAIN off the DoD NIPR network without a CAC connected, 2FA is mandatory. It ensures only you can sign in — even if your password is compromised.

What you'll need

Install an authenticator app on your phone — Microsoft Authenticator or Google Authenticator both work. Then follow the steps below.

Go to login.dso.mil using a computer with your CAC card inserted and reader connected.
Click Authenticator in the top-right corner of the Platform One window. Then on your phone:
  • Open your authenticator app and tap Scan a QR code
  • Scan the code on screen — a 6-digit one-time code will appear in your app
  • Enter that code into Platform One's One-time code field and give the device a name (e.g. "iPhone")
In Platform One, navigate to the Password menu. Enter and confirm a new password, then click Save. You're now ready to log in from any device.
