Firebase UI authentication with google fails with message (code:10 message:10)

I've made a chat app that uses Firebase's feature Real-time database. I face a problem with google authentication. The problem started when I downloaded the app from the Play Store, the authentication was working perfectly when I was running the app in debug mode. When users try to sign in they get a toast message code:10 message:10.

I would like to note here that: I've added the SHA1 fingerprint. How can I solve this?

*Not sure if this is helpful but I've followed step by step this tutorial

Solution 1:

You need three keys in order to make it work:

1. The debug key. Informations here.

2. The release key. Informations here.

3. Google Play App signing key. Informations here.

All these keys are needed in order to make the sign-in process work.

Other informations here.

Solution 2:

After generating SHA1 for release key, I forgot downloading the new google-service.json file that caused the same error.

Make sure you follow the instruction https://developers.google.com/android/guides/client-auth to generate and add debug/release SHA1 to firebase console and download google-service.json after updated.

If you use Use app signing by Google Play option, you need an additional step:

After uploading app into google play console, go to Release management > App signing, copy SHA1 and paste to firebase console

Update

In the new google play console, the App signing key can be found as following: Setup > App signing

Solution 3:

Make sure you have added signed SHA1. If you are using debug one then it will not gonna work for live apk.

You need to put "debug.keystore" in this path C:\Users\USER_FOLDER_NAME.android

then in Android studio follow the below steps 1. Run your project 2. Click on Gradle menu 3. Expand Gradle Tasks tree 4. Double click on android -> signingReport

You can see SHA in Run Tab
