Thanks for your feedback. As Google Sheet generate unique enough link it's almost same secure as password / access token (if you do not post link everywhere :) same as with your password). Alternative is open access via OAuth to all Google Sheets documents on Drive so many users prefer to open access to one file via link instead. Anyway we are working on OAuth authorisation as an option.
Permission for the Google Sheet is "anyone with the link" can access it? No, thanks I'll pass on that
