There are several new add-in apps that tie into google docs and sheets as discussed here. The one I'm interested in is AppSheet, which I think might give a better interface for inputting spreadsheet data into google sheets. When I try to use the app, it asks me to authorize access to my Google sheets by inputting my google name and password. The password screens LOOK like they come from google, but this smells fishy to me. Launching an app and entering username and password from within the app seems just like following an email link and entering a username/password....it's to easy for the email sender or app developer) to spoof the legitimate login screen and read my username / password. I realize the app needs (limited) access to my google account, but there's got to be a better way than putting my google username/password at risk. What do you think: Is this the standard approach for all of the new add-in apps? Is there any way to authorize limited account access without entering google username/password FROM WITHIN THE APP? ...if not, thouldn't there be?
