Newbie-adding ecobee to Home Assistant help

Hi-I am brand new to Home Assistant and my brain is 73 years old so this is a new challenge for me and my brain.
I want to add my ecobee to Home Assistant and I went to the website to get an API and entered my ecobee email address and password. The screen comes back to enter it again. So I did. And again, etc… It never goes any further. What am I doing wrong? Thank you, Judy
