New to Pi; Need help with installation of Hassbian 1.3

Just got my Pi3b;
After several failed attempts of installing Home Assistant.
Just installed[Hassbian 1.3 - A bit of a Stretch] image file onto my sd. It appears to have worked. At initial boot, it’s asking for hassbian login & password.
It is not: pi, raspberry. I tried that.
How do I break out of that to configure my wireless connection, change the pi’s name and password pi configuration stuff.
