Authenticate using service account?

[rtassicker]

First thankyou for your great introductory python resources Al, they've been a very useful learning tool for me.

I've built a simple tool using ezsheets and my bank's API to produce a fortnightly budget spreadsheet but one irritation is that my oauth2 token expires after 7 days, so I need to authenticate again every time, or I can publish my "app" in the Google API dashboard which means submitting a bunch of stuff for verification that only seems relevant to a commercial app. Since this is just for my use I don't want to do that.

I've seen suggested as an alternative to use the service account authentication (https://developers.google.com/identity/protocols/oauth2/service-account) - could ezsheets be adapted to authenticate with google this way or is there another library you'd recommend?
