This solved it for me. This has been a wild ride!!!! A lot of the stuff you've done, I found in dribs and drabs all over the internet and had done already. As you noted early on, Google has changed things and not yet updated their documentation. The how-to articles don't connect a few CRUCIAL dots in this puzzle. For me, it was using that auto generated oauth client id and client secret everywhere throughout my app. Thanks for putting this video together.

Thanks for this video, I was having serious issues with the old package and the documentation for the new package is not the greatest. The github guide really helped too thanks!

This video is the best of any 11.01 video I've seen

Seriously, I respect and appreciate you guys. And Google should reflect. It seems that it has become a different system from version 10 to version 11.

I was confused at the part where "OAuth 2.0 Client ID" was designated as the web-client automatically generated by Google service (I already made one myself, so I thought it should be done), but in the end, through your video and kind Git, I couldn't solve it for 3 days The problem was solved in 3 hours.

How did you find the client secret? I just can’t find it anywhere

[JoeHobbiesfun]

Thank you this works for me, can you please make video for connecting firebase auth with firebase database as well?

[TwixtorAnimeFree]

it's very help thanx!!!
first i just wanna ask, this test login must be uploaded to playstore first?

[Redping]

Hi I'm Korean and your videos and materials have been really helpful for me. I always want to know how you find out and create this information because I only know how to do google and youtube searches.Thanks again

[mysteriousanayasman]

Thank you so much, I was struggling with Google Play Authentication as I searched YouTube along with the documentation and it was a mess and I had to discard it all and ended up using anonymous and manual sign up with an Email and password within Firebase.
I have an enquiry; how to activate App Check in the firebase within Unity?

[MartianHunter]

Hey, can you share the process of google auth login with firebase (without playgames).

[PirateDave]

Hi, thank you for this video. I finally undestand how to connect Firebase to Google Play Service.
But afterwards I fall into another issue. This is working for me only on local and/or internal test mode. As I upload app to Play Store it doesn't connect anymore.
I've try to change the client secret file (from Upload to Signin key) but it's not working.
Any help is accepted.
Thanks anyway ...

Hey, I need help with the Leaderboard. The Google Play Authentication works perfectly. But my leaderboard only shows up one score from the same user. There is no user who can uploud their own score, to display himself with more than 1 player in the leaderboard
Can You help?

[gorik]

Hi, I have problem, I download apk, and displayText is always "canceled", when I launch .apk, should I upload to tests on google play console?

[jendimir]

Thanks for the guide The Web Client secret in firebase can be different then the Client secret in Google Cloud? or i should rewrite the Firebase one so it matches the googles one
