I have installed Magento 2.1.0 successfully on August 25th.
Now I want to upgrade to 2.1.1 (and maybe 2.1.2)
a) there is no upgrade facility via Softaculous (as there used to be for Magenti 1.x)
b) I am not able to do it via Magento SetupWizzard/Upgrade or Composer update* as it is requesting credentials and my Magento 'username' and 'password' are not accepted and I don't find any in my Magento account.
