I have forked Chinmay's gist and updated it to pull the device serial from aws instead of hardcoding it. I have also updated the exits to return a status of 1 instead of just exiting.

I am using it in deploy scripts like this (I renamed the script to awsMfaCli.sh):

. awsMfaCli.sh
script_status=$?

if [[ $script_status -ne 1 ]]; then
    echo "Building production"
    if npm run build ; then
       echo "Build Successful"
    else
      echo "Error building, exiting.."
      return 1
    fi


    echo "Removing all files on bucket.."
    aws s3 rm --recursive s3://mybucket

    echo "Uploading site.."
    aws s3 sync build/ s3://mybucket
    echo "S3 Upload complete.."
    echo "Deployment complete."
else
    return 1
fi
