I have the same error, in my case with Firebase Phone Auth, and the code didn't sent to some Carrier in my country and shown the same error. You need to add another Auth method for users or try sending OTP by third party service.

Try this:

go to https://console.firebase.google.com/

choose your project; click authentication -> get started; choose email and password -> enable;

this worked for me

Actually in my case, Flutter Fire was not configuring project correctly through cli. There was a difference in Api keys written in firebase_options.dart file and the Api keys written in google-service.json and GoogleService-Info.plist files for iOS and Android Apps.

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 Google Cloud Console.

  2. Open APIs & Services -> Credentials tab.

    enter image description here

  3. Open your keys Android/iOS/Flutter.

  4. Select "Don't restrict key" or carefully check APIs you want to enable.

In my case, I had Blocking Functions that verify users before account creation using beforeCreate(). I actually forgot I had it there and it was blocking all signups.

Wish the error message would be a bit more specific instead of internal error.

Don't forget add DynamicLink the url which added in Sign-in Domain in Authentication

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.

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

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