I have reinstalled the phone app on my wife's phone. I've entered what I think is the password but its not.
PS. It would be nice to have the option to view the password, after all we are not supposed to use easy passwords and one fat finger slip and ....
I can remove and add guest users but there there is no ability to set passwords on that screen. Just to be sure I removed and readded the account, but now I am not sure what state the password is in.
Found it. Thank you for your help.
