I am trying to setup my own smart devices, but of course I want the user to authorize before logging in to my application. I would rather not do it with OAuth, simply because Google Sign-in is way easier. However, this can only be enabled when you set the Do you want to allow users to sign up for new accounts via voice? option to yes
. Unfotunately this option does not seem to be there in the actions console.
What is the reason I can't select this? Are there extra requirements for it?
Smart home actions do not support Google Sign-in. You can only use OAuth.
