Usually, you need to fastidiously guard API keys (for example, by using a vault service or setting the keys as environment variables); however, API keys for Firebase services are ok to include in code or checked-in config files.</p> <p>Although API keys for Firebase services are safe to include in code, there are a few specific cases when you should enforce limits for your API key; for example, if you're using Firebase ML or using Firebase Authentication with the email/password sign-in method.

By default, all of your project's Firebase Apps <em>for the same platform</em> (iOS vs Android vs Web) will use the same API key.</p> <ul> <li><p><strong>Firebase iOS Apps</strong> — Find an app's auto-matched API key in the Firebase config file, <code translate="no" dir="ltr"><nobr>GoogleService-Info.plist</nobr></code>, in the <code translate="no" dir="ltr">API_KEY</code> field.</p></li> <li><p><strong>Firebase Android Apps</strong> — Find an app's auto-matched API key in the Firebase config file, <code translate="no" dir="ltr"><nobr>google-services.json</nobr></code>, in the <code translate="no" dir="ltr">current_key</code> field.</p></li> <li><p><strong>Firebase Web Apps</strong> — Find an app's auto-matched API key in the Firebase config object, in the <code translate="no" dir="ltr">apiKey</code> field.</p></li> </ul> <h3 id="use-api-keys" data-text="Using an API key">Using an API key</h3> <p>API keys are used to identify your Firebase project when interacting with Firebase/Google services. Specifically, they're used to associate API requests with your project for quota and billing. They're also useful for accessing public data.</p> <p>For example, you can explicitly use an API key by passing its value into a REST API call as a query parameter. This example shows how you might make a request to the <a href="/web/20210426052445/https://firebase.google.com/docs/reference/dynamic-links/link-shortener">Dynamic Links link shortener API</a>:</p> <pre translate="no" dir="ltr"> POST https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=<var translate="no">API_KEY</var> </pre> <p>When your app makes a call to a Firebase API, your app will automatically look in the Firebase config file/object for your project's API key. You can, however, set your API keys using a different mechanism, including environment variables.</p> <h2 id="apply-restrictions" data-text="Apply restrictions to API keys (recommended)">Apply restrictions to API keys <em>(recommended)</em></h2> <p>Although it's not necessary to treat an API key for Firebase services as a secret, there are some specific cases (see below) in which you might want to take additional measures to protect your project from misuse of the API key.</p> <aside class="note"><strong>Note:</strong><span> If you apply restrictions to an API key that's used for accessing Firebase services, and you're getting errors, you may need to include the Firebase Management API in the list of allowed APIs. This is especially true if you use Google Analytics with a web app.</span></aside> <aside class="caution">If an API key is currently in use by a production app, you need to be cautious about adding restrictions to that API key. You should test your restrictions in a testing app and with a <a href="#test-vs-prod-keys">test API key</a> before adding any restrictions to your production API key.</aside> <h3 id="apply-restrictions-password-based-auth" data-text="Password-based authentication">Password-based authentication</h3> <p>If you use password-based Firebase Authentication and someone gets hold of your API key, they will <strong>not</strong> be able to access any of your Firebase project's database or Cloud Storage data <em>as long as this data is protected by <a href="/web/20210426052445/https://firebase.google.com/docs/rules">Firebase Security Rules</a></em>. They could, however, use your API key to access Firebase's authentication endpoints and make authentication requests against your project.</p> <p>To mitigate against the possibility that someone might use a stolen API key to attempt a brute force attack, you can tighten the default quota of the <code translate="no" dir="ltr">identitytoolkit.googleapis.com</code> endpoints to reflect the normal traffic expectations of your app. Be aware that if you tighten this quota and your app suddenly gains users, you might get sign-in errors until you increase the quota. You can change your project's API quotas in the <a href="//web.archive.org/web/20210426052445/https://console.cloud.google.com/apis/api/identitytoolkit.googleapis.com/quotas?project=_" class="external">Google Cloud Console</a>.</p> <h3 id="apply-restrictions-ml-cloud-apis" data-text="Firebase ML and Google Cloud APIs">Firebase ML and Google Cloud APIs</h3> <p>Although API keys used for Firebase services do not generally need to be treated as secret, you should take some extra precautions with API keys used to grant access to Firebase ML and Google Cloud metered services.</p> <p>For example, if you use Firebase ML's Cloud Vision APIs on iOS, you should create separate API keys that you use only for accessing the Cloud Vision APIs as described in <a href="/web/20210426052445/https://firebase.google.com/docs/ml/ios/secure-api-key">Protect your Firebase ML iOS app's Cloud credentials</a>.</p> <p>If you use any other Google Cloud API (on any platform) that is not automatically enabled by Firebase, you should consider also creating separate API keys for use with those APIs. See the Firebase ML document linked above for an example of how you can accomplish this.</p> <p>By using separate API keys for non-Firebase APIs, you can rotate or replace the keys when necessary and <a href="//web.archive.org/web/20210426052445/https://cloud.google.com/docs/authentication/api-keys#api_key_restrictions" class="external">add additional restrictions to the API keys</a> without disrupting your use of Firebase services.</p> <h2 id="test-vs-prod-keys" data-text="Use environment-specific API keys (recommended)">Use environment-specific API keys <em>(recommended)</em></h2> <p>If you set up different Firebase projects for different environments, such as staging and production, it's important that each app instance interacts with its corresponding Firebase project. For example, your staging app instance should never talk to your production Firebase project. This also means that your staging app needs to use API keys associated with your staging Firebase project.</p> <p>To reduce problems promoting code changes from development to staging to production, instead of including API keys in the code itself, either set them as environment variables or include them in a configuration file.</p> <p>Note that if you're using the Firebase Local Emulator Suite for development along with Firebase ML, you must create and use a debug-only API key. Instructions for creating that kind of key are found in the <a href="/web/20210426052445/https://firebase.google.com/docs/ml/android/secure-api-key#3_create_and_use_a_debug-only_api_key">Firebase ML docs</a>.</p> <h2 id="faqs" data-text="FAQs">FAQs</h2> <p><section class="expandable" id="faq-invalid-api-key"> <h4 class="showalways" id="faq-invalid-api-key" data-text="I got an email or error that my API key is invalid.
