Asking for password when easy access granted


I am using 2 Mac computers. Both of my Mac computers are in my "My Computers" group and easy access is granted for both. From Mac A I am trying to connect to Mac B. When on Mac B, I have turned off random password generator and tried to delete the password when I am on the app on that computer, but if I look at the properties, it looks as though a password is set. I tried the computer log in password but that doesn't work and I don't remember setting a password in TeamViewer for Mac B. I also tried going to the properties via web browser of Mac B and I changed & saved the password but this still doesn't seem to work.
