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?

Solution

  • 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.
