Authentication for an Alexa skill

[Scott Lundberg]

I have been working on getting account linking working for an Alexa skill using email/password authentication in Firebase. I can get it to work using an implicit grant for the lifetime of the token returned by getToken(), but then of course the token expires and needs refreshed.

It seem like there should be a way to use the OAuth code grant process similar to how http://matchboxmobile.com/blog/oauth-using-alexa/ does for Facebook authentication.

Is there any precedent for using Firebase with Alexa skill linking?

Thanks!
