I am using flutter web and firebase authentication to build a web app. For that 1. Created Firebase app with Google signin as one of the sign in methods. 2. Added the dependencies as given in https://github.com/FirebaseExtended/flutterfire/tree/master/packages/firebase_auth/firebase_auth/example and https://dart-pub.mirrors.sjtug.sjtu.edu.cn/packages/firebase_auth_web.
When I try to login, the Google sign-in window appears. Once I enter the email address and press enter, it gives the following error.
"Couldn't sign you in This browser or app may not be secure. Try using a different browser. If you’re already using a supported browser, you can refresh your screen and try again to sign in."
I used Chrome browser. What should I do to make my app more secure ? For android, we had the option of using SHA keys to encrypt the connection. Do we need to do something similar for web ?
The issue was with the chrome developer version Flutter use to launch as a device. If we open the same URL (localhost:portnumber) in the normal chrome, it will work without any issue.
