Can I have a 2nd user access my account?

Question:

I just installed the ecobee3 lite, set up an account with my email address, got it working on my phone and life's awesome. For me. And only me. How can I make life awesome for my Wife as well? I'd like her to be able to set the temperature from her phone. Does she need to use my credentials?

Answer:

The ecobee thermostat can only be registered to one email at this time, you would need to simply share the credentials (email address and password) with any other user that needs to access the mobile app. The same credentials can be used to login from another phone.
