You need to add the SHA1 of the production certificate in Fireabase. Check this link

  • For my case, I added all SHA1 and when I generate a signed .apk and install on the phone, everything works fine but when I published a signed .aab bundle, an error comes "This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console" Kindly advise me, this has taken me over 4 days but no success. – Neri Oct 14 '18 at 07:33

You are having fingerprint certificate in console, but its only for debugging purposes, for signed apk you need a production fingerprint certificate, and you can get one by

c:\Program Files\Java\jdk1.6.25\bin>keytool -list -v -keystore c:\you_key_here.key

It's simple, download (KeyStore Explorer 5.3.2) and open your .jks file using KeyStore Explorer it will ask for a password, enter your password that you entered at the time of generating signed apk. Then once it gets opened click on entry name there you will see Fingerprint SHA-1 key like (10:02:A6:3E:A9:68:83:FE:F2:66:6F:F8:C4:9D:FF:3C:C2:EA:76:96) this is fake SHA-1 ok, Here
