Optionally, you can use the option

customizations

 to change the look of the authentication screens. This does not apply to the actual sign-in buttons and their position. What you can change depends on the platform.

##### Android The values available for android customization are as follows,`javascript const config = { ... customizations: [ 'theme', 'logo' ], };`First add FirebaseUI in your build.gradle (:app),`javascript dependencies { implementation 'com.firebaseui:firebase-ui-auth:6.4.0' ...`Fortheme, add the next style in your styles.xml, then copy into the drawable folder an image to use for background and name it auth_background.png.`javascript`Forlogo, copy an image in the drawable folder and name it auth_logo.png. ##### iOS The values available for iOS customization correspond to specific screens and are as follows,`javascript const config = { ... customizations: [ 'auth_picker', 'email_entry', 'password_sign_in', 'password_sign_up', 'password_recovery', 'password_verification' ], };`Open your project inXCode and add the .xib file of the screen you want to customize. The .xib files are located in ./ios/custom-screens/ of this library. Let's say, you want to customize the auth-picker screen, add the file FUICustomAuthPickerViewController.xiband use the XCode tools to add it labels, images, change colors, and so on.

`$3`



You can control whether new users can sign in or not by using the option

allowNewEmailAccounts. Also, if you do not want to require the user name during sign up you can set the option requireDisplayName

 to false.

javascript

  const config = {

    ...

    allowNewEmailAccounts: false,

    requireDisplayName: false,

  };





$3

When an anonymous user signs in or signs up with a permanent account, the

autoUpgradeAnonymousUsers

 option allows you to link the existing account (anonymous) with permanent account. This way the user can continue with what they were doing before signing up. By default this option is disabled.

javascript

  const config = {

    ...

    autoUpgradeAnonymousUsers: true,

  };
