Answer 1

what worked for me was combination of the other answers:
.. Enable Android Device Verification per answer from @Tippu Fisal Sheriff
.. get SHA-1 and SHA-256 keys by running ./gradlew signingReport from terminal, android folder per answer from @Sarwar Ahmed & @Malcolm Deck
.. on firebase website, going to project settings and 'add fingerprint" answer from from @Sarwar Ahmed

Answer 2

You need to add fingerprint to your firebase project as below simple way

1. Goto your android studio and open Gradle tab from right corner.

2. Your app name > Run Configuration > ..[signingReport]> double click

3. See your Terminal window from bottom and copy both SHA-1 and SHA-256 lines

4. Goto firebase.google.com > choose your project > project settings > general

5. Click on add fingerprint and paste your copied keys without including SHA-1 or SHA-256 name

6. Click add and re launch the app.

Answer 3

Step 1: Select a Project.

Step 2 : Enable Android Device Verification

Use below the link to Enable Android Device Verification.

https://console.cloud.google.com/apis/library/androidcheck.googleapis.com

Answer 4

Your problem related to SHA1 and SHA256 keys. You have to add them to authenticate your certs.

• List item

• Goto

  Firebase Console of your project Authentication Project Setting (From Setting button near Project Overview) Add fingerprint Add SHA-1 and SHA-256 values of your keystore. You can get keystores from gradle like this.

./gradlew signingReport

Read this for more information: https://firebase.google.com/docs/auth/android/phone-auth#enable-app-verification

Answer 5

Ah, it looks like you need to add a SHA-1 Certificate Hash to your application registration in the Firebase Console. I think you can find instructions to do that here
