you can change root password if you log in as pi and $sudo passwd root
On other fronts, I too have set this up on a raspberry pi zero and have had no luck getting dnsmasq to start correctly or hand out IPs. The AP is broadcasting, but no IPs are assigned.
Edit: Fixed it
sudo nano /etc/dnsmasq.conf
# Uncomment this to enable the integrated DHCP server, you need
# to supply the range of addresses available for lease and optionally
# a lease time. If you have more than one network, you will need to
# repeat this for each network on which you want to supply DHCP
# service.
next line change to:
dhcp-range=192.168.77.10,192.168.77.150,12h
sudo reboot
