href="https://github.com/firebase/firebaseui-ios">FirebaseUI</a> is a library built on top of the Firebase Authentication SDK that provides drop-in UI flows for use in your app. FirebaseUI provides the following benefits:</p> <ul> <li><strong>Multiple providers</strong>: sign-in flows for email/password, email link, phone authentication, Google Sign-In, Facebook Login, and Twitter Login.</li> <li><strong>Account management</strong>: flows to handle account management tasks, such as account creation and password resets.</li> <li><strong>Anonymous account linking</strong>: flows to automatically link anonymous accounts to identity providers.</li> <li><strong>Customizable</strong>: customize the look of FirebaseUI to match your app. Also, because FirebaseUI is open source, you can fork the project and customize it exactly to your needs.</li> </ul> <h2 id="before_you_begin" data-text="Before you begin" tabindex="-1">Before you begin</h2> <aside class="note"> <b>Note:</b>
