# Firebase Crashlytics

Modular API method `isCrashlyticsCollectionEnabled(crashlytics)` has been removed, please use the property on Crashlytics instance
`getCrashlytics().isCrashlyticsCollectionEnabled` instead.

# Firebase Auth

```js
const credential = await signInWithEmailAndPassword(getAuth(), 'dummy@example.com', 'password');

// Use below - remove any instances of `multiFactorUser.enrolledFactor`
console.log(multiFactorUser.enrolledFactors);
