@tatiang @muneer @domhnallohanlon @darren Hi, I am currently facing an issue with sign in / sign up for my app. When trying to login or create a new account, I get the error ‘Your API key is invalid, please check you have copied it correctly.’ However, I have made 100% sure that I copied the API key correctly from Firebase. I have searched this forum and have seen that people have run into similar issues but I have not seen a clear reason as to why this is occurring and how I can fix it. Below is a link to the project. Any help would be much appreciated. [https://x.thunkable.com/copy/74aaec716e7ef96c090faa5bc9fe3a7d](https://x.thunkable.com/copy/74aaec716e7ef96c090faa5bc9fe3a7d) Thanks! ---

Yes, a web app has been created, I have tried making a new Firebase project entirely and copying the new API but it still did not work. ---

I tested your app using my API key and Database URL and it is working. One thing that worth noticing.

@muneer I have checked the server location, however, it is ‘United States (us-central1)’, so I do not think that is the problem. Would you possibly mind sharing your Firebase configurations / settings (with any details blurred out of course) so I can see if there is any discrepancies with mine? ---

I think I may have discovered what the issue is. When I live test the project on my machine, the error does not appear. however, when I have shared the project link with other people and they try to run it, the error message comes up. I have just noticed the only one firebase account is allowed per project, therefore when they make a copy of the project and run it, it is not allowing the app to connect to Firebase since the Web API is already in use. ---

What do you mean by copying the project? If you mean within Thunkable then the problem is when you share a project Thunkable will automatically remove the keys. This is a security issue. Those copying your project should use own keys unless you share the keys with them. ---

Right. The other option is to publish the app with your Firebase settings and then everyone who uses the app automatically uses your settings. ---
