What is the difference between the web API key and key under "Your Apps"
14:10 02 Nov 2025

I noticed that in my Firebase project, under Project Settings > General, the value beside "Web API Key":

web api key

is different from the apiKey value in the Your Apps section just below that:

Your Apps api key

Why are these two keys different? I noticed that my Google Auth sign-in method only works when I use the Web API Key. I can't seem to find any information on the difference between these two keys.
