Firebase - What is the API Key

Question

In Firebase, when we sign up , it gives us an API key for each firebase Url. But where is it used in a consuming application? The fireBase API does not provide any means to supply API Key.

Security : What prevents anyone to go ahead and write any object to the given firebase Url? How is the authorization managed?

For people looking for the 3.x and above API Key to insert in your initializeApp() config, see docs here: https://firebase.google.com/docs/web/setup#add_firebase_to_your_app — Kato, Jun 10 '16 at 18:24

You can generate your api key at https://console.developers.google.com/apis/credentials?project=[YOUR-PROJECT]

Replace [YOUR-PROJECT] with your proyect ID.

updated the links to the new Firebase website

Your question is very timely, as Firebase just announced its full security suite a few days ago.

There's a nice intro screencast and docs here: https://firebase.google.com/docs/database/security/

The "API Key" is the old name for a Firebase Secret. This is used to generate Authentication Tokens to prove to Firebase who users are. You can see docs on authentication here: https://firebase.google.com/docs/auth/

I did as the document says, but trapped by the error `FirebaseAuthClient is not defined` as I'm trying to use new `FirebaseAuthClient()`. So, what's wrong? – Kinka Dec 24 '12 at 11:09

OK, I know... I **need to add the Firebase Simple Login JavaScript include**, but it doesn't tell us where the code exists. However, I found it at https://github.com/firebase/firetube... – Kinka Dec 24 '12 at 12:03
^ Is the correct answer. You need to include – Jason Pudzianowski Dec 29 '12 at 09:16
