Answer 1

make sure your desired method is enabled in the firebase console eg. anonymous sign-in, email/pass sign-in.

Answer 2

If enabling Sign-in methods in Firebase console/Authentication didn't help you make sure your key is not restricted in Google Cloud Platform:

1. go to https://console.cloud.google.com/
2. open APIs & Services -> Credentials tab
3. open your keys Android/iOS/FLutter
4. Select "Don't restrict key" or carefully check APIs you want to enable.

It helped in my case, hope it helps you as well. Cheers!

Answer 3

My issue was that my simulator had cached a user from a different project (I have dev/prod firebase projects)

I had to log out and register again.

Hopefully, this saves someone as much head-scratching as I've just been through.

Answer 4

仍然遇到相同问题的任何人都可以重新启动模拟器或检查您的互联网连接

Answer 5

Do also double-check the values in your GoogleService-Info.plist. I got this same error after using an incorrect API_KEY.

Answer 6

不要忘记在Authentication中添加在Sign-in Domain添加的DynamicLink的动态链接
