title: Is it possible to sign in with Google account using webview on my app?
body: <p>I'm creating an app with youtube video search function using jsoup. Now I want to get the list of channels the user has subscribed, I found an app with similar functionality on play store.</p>

  <p>This application uses webview and access to Google login page, after the user is logged in, the application can get the list of channels and the user's watch history.</p>
  <p><a href="https://i.stack.imgur.com/X8Y7M.jpg" rel="nofollow noreferrer">Login page</a></p>
  <p>I tried it and was able to do the same.</p>
  <p>I think would be a security risk, the application may access the user's personal information, but why is it not prevented by Google?</p>
