Cannot connect DaikinOne plus to HA using integrator token

I have three DainkinOne plus thermostats and received the Integrator token of 1700 characters or such. From the Daikin Integration process I get the prompt to enter host which I enter any one of the three IP address verified by pings then enter the integrator token. if I include the Daikin could password I receive “Invalid authentication, use either API Key or Password.” If I leave off the password I receive “failed to connect” to any thermostat. Any thoughts on this?
