How do use the Email Sign In By Firebase component because when I use it, I connect Thunkable with API Key and Database URL from Firebase and I use the sign in/up blocks correctly. I use things like below. Can you please help me figure out why it is saying “Invalid API key, please make sure you have typed it correctly”?
It will give you Invalid API key message even if the problem is in the Database URL.
Check that both are correct.
Did you enter into Thunkable the Web API Key shown in your Firebase console under “Project settings” → “General”?
