@sparker, TRIGGERcmd Smart Home is an Alexa skill, not something you install on your phone, so now I'm not sure if you're talking about the TRIGGERcmd iOS or Android phone app.
I wonder if you logged into your account using the "Login with Google" button? If so, you'd need to set a password in your profile page before logging into the phone app with a email/password. The phone apps allow you to use a pair code to login, so you could also try that instead.
If you're talking about the Alexa skill, you could try enabling it on you computer instead. If you use the same browser where you're logged into triggercmd, it won't even prompt for login when you enable the skill.
