Next, click the +
button in the top right corner of the Google Authenticator app on your phone, and then select ‘Scan Barcode’.
On the AWS console, click ‘Show QR Code’.
Now you should use your phone to take a picture of the QR code displayed on the AWS Console.
You will see a new entry in the Google Authenticator app showing ‘Amazon Web Services’ and your account number and username below.
You will need to enter two six digit codes, they rotate so you will need to wait for a new one once you have entered the first.
Once both codes have been entered on the AWS console, you should click ‘Assign MFA’.
