Unity User Login System Tutorial - Firebase Authentication

[@xzippyzachx]

*IMPORTANT!!!* These are some common issues and changes that are required since curtain parts of this tutorial are out of date. - The package manager is no longer used to install the Firebase packages and therefor the package resolver will no longer appear when installing and the Firebase packages will not appear in the package manager when installed. If you have issues installing the Firebase packages start by removing any Firebase assets you may have in your project. Download the newest .unitypackage file from this link developers.google.com/unity/archive#firebase_authentication. Then in Unity go to Assets > Import Package > Custom Package. Now import the .unitypackage you downloaded. This will install the Firebase core and Firebase auth packages into your Unity project. - There are also some code changes since this video was recorded. Make sure to check the GitHub repo for the most up-to-date code. If you still have issues feel free to open a help post on my Discord server: discord.gg/7rGAAqC

@Politically WOKE Hindus It should but I would download the Firebase .unitypackages from this link instead. The unity package manager no longer works with the Firebase packages

[@alfombraxd4910]

I had this error when importing it: Assembly 'Assets/Firebase/Editor/Firebase.Editor.dll' will not be loaded due to errors: Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform? And I fixed it by installing iOS support in Build Settings, even though I only wanted to build it on Android. Also it didn't show in Package Manager, only in Assets.

[@RugbugRedfern]

Great tutorial! Thanks for making this. Rule of thumb: with starter projects, make them as simple as possible. This means no fancy UI, no custom fonts, and no blurred backgrounds. Making it as complicated as you did will just make it harder for others to change and use in their own project. edit 7/27/22 sorry for being so critical love u zach

[@xzippyzachx]

Yeah I could see that, but I also wanted to make it look good so that viewers would know its a good tutorial.

[@RugbugRedfern]

​@@xzippyzachx In my experience it doesn't really have an impact on the viewers' perception of the tutorial. And it just causes more problems than it helps. I'm just saying its a lot harder to customize and make your own as a user. It can also be more confusing to a beginner because they might not understand how the stylized buttons work of how to use the custom font. Either way, you can do what you want. But in my opinion it does more bad than good.

Hi, there are some things i notice that are different from yours.. 1) once you downloaded the Firebase Unity SDK (Zip) and you extracted it, I see your file name as 'firebase_unity_sdk_6.15.2' in this video. Mine after extracting only says 'firebase_unity_sdk'.. before extracting, mine was saying 'firebase_unity_sdk_12.1.0.zip' 2) In your video, when importing package and after you clicked 'firebase_unity_sdk', you have either 2 options 'dotnet3' or 'dotnet4'.. For me, I don't get those options and instead, it just directs me to 'FirebaseAuth.unitypackage' like how you do in this video.. the only difference is, i dont have the option to click 'dotnet4' 3) After you clicked 'import' in 'Import Unity Package', it automatically shows you the 'Package Manager Resolver' window.. For me, it doesn't show this window.. As a result, when I hover over to Windows>Package Manager> In Project, I don't see the Firebase Authentication in there at all Pls help, thankss

[@xzippyzachx]

1) Thats fine its just different naming 2) and 3) The method to install Firebase has changed since I made this tutorial. The Unity package manager is no longer used.

I'm creating a login and registration for Students to take their MCQ test (they'll have to login and upon successful login, they'll be directed to the test database) So currently I have 2 respective groups: Admin (Teachers) and Trainees (Students) For the Admin, they will have a login button and registration button. I shld be able to follow your video for that without a problem. But however for the trainee scene, I only need to have a login button. So that means that if they are new and need to create a new account or reset password, it is the Admin's responsibility to do it for them. Can I get your help with this and what would be different?

[@BrettClimb]

Thanks, this is very helpful! I'm wondering what the next step is in terms of using the fact that the user is logged in. Does Firebase send the user some kind of authentication token once they have logged in, which can be used to verify their identity on a custom server? I'm imagining that the front-end temporarily stores that auth token, sends it to my Node Express API, my API then sends the token to Firebase to verify that it's real, and then I can provide the user with access to the back-end services that they have purchased. Does that sound right or am I confused about this process?

[@xzippyzachx]

That sounds exactly correct. I would look through the Firebase documentation to find specifics on how you can do this. You can also ask questions on my Discord and I will try to assist where I can.

[@Ermelious]

How expensive is it on Firebase if let's say it's used for a multiplayer game? Something like fortnite. I'm guessing they only use database to store player information like items, in-game currency and score and this might not be called as frequently as those real-time action stuffs like handing player movement correct? We would only be making calls to firebase when the game ends, during login, and when purchasing / trading items. The Free firebase tier can store only 1GB of data and I believe there are some other limits like the calls per month. Based on the above scenario, will it wipe out 1GB of data per month making the Free tier insufficient? How many players do you think the free tier can handle? I've search some threads on reddit but can't seem to find any relevant discussions yet. If its going to be expensive are there alternatives to firebase? What about AWS? Or is there any free offerings? I guess if it turns out that the Free version maxes out at 100-1000 players then, maybe for the sake of trouble down the line, some would just be better off linking it to a local database with sql or something similar when starting out as that should offer at least an option to have it hosted by multiple servers in future if required?

[@xzippyzachx]

The potential cost is a hard question to answer. Its really hard to estimate because no one really knows exactly how much bandwidth their application will use. Which ever route you go it will cost you money at some point but as you said going a custom SQL database solution might be the smarter option so you can switch hosting providers in the future.

sir I have question my firebase not working on mobile when I build my project to .apk, but it working on editor in unity on pc. How to fix it. Thank for answer

[@xzippyzachx]

I suggest getting a mobile console so that you can see any possible errors that are being thrown on mobile

[@time6385]

@@xzippyzachx I already solve it. If I have question again, I will join your discord to ask for help. Thank for reply

I get an error saying its something to do with iOS. I thought we downloaded for Android?

[@xzippyzachx]

You may still need to have the IOS build module installed for your Unity version. Even if you aren't going to build for IOS

[@Gtclanagar]

Would this work with IOS and Android as well? Or do I need to do certain things to get this to work? Thanks for the Tutorial!

[@xzippyzachx]

You should just have to change the project type in the Firebase console

Brother, I've faced a problem... I'm using 2021.3.25f1 version... It's saying that Cannot Implicitly convert type Firebase.Auth.AuthResult to Firebase.Auth.FirebaseUser

Try "User = LoginTask.Result.User;" instead. You can also ask for help on my Discord server.

Will this method also remember the user and does not ask for login credentials again?

[@xzippyzachx]

Yes Firebase automatically auto logs in. You can do a simple check to see if the user variable is null when the game starts and if its not null then skip the login screen. Ask on my Discord server if you need help.

Hi, thank you for the amazing tutorial. Sadly, I get two errors and can't register new users :( Maybe you know what causes this? 1. "Database URL not set in the Firebase config." 2. "Failed to register task with System.AggregateException: One or more errors occurred. ---> System.AggregateException: One or more errors occurred. ---> Firebase.FirebaseException: An internal error has occurred. "
