title: How to get one access token/refresh token for indefinite use (oauth2 - Spotify API)
body: <p>I'm developing an application that will only use one Spotify account ever, and I don't quite understand the refresh token (using oauth2). Ideally, I'd like to just use the Spotify API console to receive an access token and refresh token once that I can use forever and not have to worry about authorization again while the application is running. If I have a refresh token, can I just use that refresh token forever or do I need to constantly get a new token with that refresh token whenever I want to access the API?</p>
