Login without credentials? – Correction

Sorry, here is a correction. I typed again mydomain.com/wp-admin and mydomain.com/wp-login, but I was not allowed to enter. In the first case the reason was probably that I was already on the Dashboard when decided to make a try how the renamed and the old URLs are working. Then the /wp-admin really worked and allowed to enter.
