title: API key not valid firebase auth
body: <p>I've had used a firebase account for my android project, and recently I faced some issues with the account so I decided to create a new one and link my project to this newly made project.</p>
  
  <p>Everything seemed to work fine, but when I tried to use firebase auth, I faced an error which says: API key not valid. Please pass a valid API key.</p>
  
  <p>I searched for hours and all I could find was that I had to redownload google-services.json file and replace it. I did it and I still get the same error</p>
  
  <p>Anyone knows what I have to do? Thanks in advance.</p>
