OAuth Token can only be used once

rivate void getCloverAuth() {
  new AsyncTask<Void, Void, CloverAuth.AuthResult>() {
    @Override
    protected CloverAuth.AuthResult doInBackground(Void... params) {
      try {
        Context context = getApplicationContext();
        return CloverAuth.authenticate(context);
      } catch (Exception e) {
        Log.e(TAG, "Error authenticating", e);
      }
      return null;
    }

    @Override
    protected void onPostExecute(CloverAuth.AuthResult result) {
      cloverAuth = result;
      if (cloverAuth != null && cloverAuth.authToken !=null) {
        mToken.setText("Token: " + cloverAuth.authToken);
      } else {
        mToken.setText("Error retrieving token."));
      }
    }
    }.execute();
  }
}

Token received for this method will only change if we reinstall the app.

How can we verify that device authentification through clover ?
