This code is part of the 2-factor authentication process.

When you set up a verified VA.gov account through ID.me, you need to set up 2-factor authentication. Authentication gives you an extra layer of security by letting you into your account only after you’ve signed in with a password and a 6-digit code sent directly to your mobile or home phone. This helps to make sure that no one but you can access your account—even if they get your password.

If you sign in to VA.gov using your existing basic or Advanced My HealtheVet or basic DS Logon account and don’t want to verify your identity, or if you sign in using your existing Premium My HealtheVet or Premium DS Logon account, setting up 2-factor authentication is optional. You can set it up during the sign-in process or any time from your VA.gov profile page.
