I am developing an App using MIT App inventor2. I want to store the data of registered users in google sheet when the users click the register button. After registering, when the users logs in, the login data should be authenticated from the registration data in GoogleSheet and let them enter the dashboard of the App if registered and if not show "wrong credential".
I could complete the registration part but could not get the idea how to log in using the data already in google sheet.
Please help!
My App .aia is attached here for you all to refer and support me please
