Back in November I posted this same question. Looking for help again since last solution was not a possible solution and the issue was closed.
I have a Nest thermostat. I also now have a new phone with a new phone number. I cannot get the Nest app on new phone to control thermostat because I cannot get logged into the account. I have tried logging in through Nest and Google since I cannot recall if I had merged them. I cannot remember the Nest password. My Google account has been updated to new phone number. When I try to select forgot pw in Nest app, it insists on sending the verification code to the old phone number. Brick wall. The solution below does not help since step 1 starts with being able to log into the Nest app.
There must be a way to either recover a log in, or reset the thermostat and start over again with new log in information.
