Go to the GCC login screen and enter your username and password. When prompted for a verification code, select I don't have my device. Enter the temporary code sent to your registered email address to complete your sign-in.Navigate to your MFA preferences:
Once you are logged in, select your name or profile image in the top-right corner, select Preferences, and click Multi-factor authentication preferences.Revoke your old device:
Under the Active factors table, locate your old mobile device and click Revoke. This will disconnect your old phone from your account.Set up your new device:
Click the Setup App button and follow the standard instructions to scan the new QR code and register the authenticator app on your new phone.
