I had the same issue but resolved it quite nicely, same with Phone Auth if you think of adding one.

Solution workers as of 23 June 2021:

  1. Go to your google play console and select your app.
  2. Go to Release->Setup->App Integrity->App Signing Key Certificate.
  3. Find SHA-1 certificate and copy it. The same goes with SHA-256 certificate.
  4. Go to your firebase console and select your app.
  5. Go to project settings and add the copied SHA-1 certificate and SHA-256 certificate. You should be able to log in with Google or Phone again. No need to re-upload apk/aab app to play store.

  • This works for me as of Dec 2021. It might take some time for login to start working after updating SHA-1/SHA-256. In my case it took around 30 minutes. – coolbootgeek Dec 05 '21 at 02:47

You should use the same key.store file for generating "signed APK" you have used for getting the sha1 key.

You should generate SHA1 for release apk also and you have to use that SHA1 to add new fingerprint in firebase and then download the google-services.json file then it will work.

I had given detail answer where all steps are described from sign in to developer account to generate SHA1 for release,to get google-services.json file

google signIn not working in release mode apk android
