apple-auth

Prerequisites to using this library

The @invertase/react-native-apple-authentication library will not work if you do not ensure the following:

You are using React Native version 0.60 or higher.
(iOS only) You have setup react-native iOS development environment on your machine (Will only work on Mac). If not, please follow the official React Native documentation for getting started: React Native getting started documentation.
(iOS only) You are using Xcode version 11 or higher. This will allow you to develop using iOS version 13 and higher, when the APIs for Sign In with Apple became available.
Once you’re sure you’ve met the above, please follow our Initial development environment setup guide.

Version 2.0.0 breaking changes

Version 2 added Android support and introduced a few breaking changes with how methods are accessed. Please see the Migration Guide.

Installation

yarn add @invertase/react-native-apple-authentication

(cd ios &&
 pod install)

You will not have to manually link this module as it supports React Native auto-linking.

Usage

Below are simple steps to help you get up and running. The implementation differs between iOS an Android, so if you’re having trouble, be sure to look through the docs. Please skip and head to the full code examples noted below if you prefer to see a more complete implementation:

iOS

1. Initial set-up

Import the appleAuth (API documentation) module and the AppleButton (API documentation) exported member element from the @invertase/react-native-apple-authentication library. Setup an event handler (onPress) to kick start the authentication request.

// App.js

import
 React
 from
 'react'
;
import
 {
 View
 }
 from
 'react-native'
;
import
 {
 AppleButton
 }
 from
 '@invertase/react-native-apple-authentication'
;

async
 function
 onAppleButtonPress
(
)
 {

}

function
 App
(
)
 {
  return
 (
    <
View
>
      <
AppleButton
        buttonStyle
=
{
AppleButton
.
Style
.
WHITE
}
        buttonType
=
{
AppleButton
.
Type
.
SIGN_IN
}
        style
=
{
{
          width
: 160
,
 // You must specify a width
          height
: 45
,
 // You must specify a height
        }
}
        onPress
=
{
(
)
 =>
 onAppleButtonPress
(
)
}
      /
>
    <
/
View
>
  )
;
}

2. Implement the login process

// App.js

import
 {
 appleAuth
 }
 from
 '@invertase/react-native-apple-authentication'
;

async
 function
 onAppleButtonPress
(
)
 {
  // performs login request
  const
 appleAuthRequestResponse
 =
 await
 appleAuth
.
performRequest
(
{
    requestedOperation
: appleAuth
.
Operation
.
LOGIN
,
    // Note: it appears putting FULL_NAME first is important, see issue #293
    requestedScopes
: [
appleAuth
.
Scope
.
FULL_NAME
,
 appleAuth
.
Scope
.
EMAIL
]
,
  }
)
;

  // get current authentication state for user
  // /!\ This method must be tested on a real device. On the iOS simulator it always throws an error.
  const
 credentialState
 =
 await
 appleAuth
.
getCredentialStateForUser
(
appleAuthRequestResponse
.
user
)
;

  // use credentialState response to ensure the user is authenticated
  if
 (
credentialState
 ===
 appleAuth
.
State
.
AUTHORIZED
)
 {
    // user is authenticated
  }
}

3. Event Listener

Set up event listener for when user’s credentials have been revoked.

// App.js

import
 React
,
 {
 useEffect
 }
 from
 'react'
;
import
 {
 View
 }
 from
 'react-native'
;
import
 {
 appleAuth
,
 AppleButton
 }
 from
 '@invertase/react-native-apple-authentication'
;

function
 App
(
)
 {
  useEffect
(
(
)
 =>
 {
    // onCredentialRevoked returns a function that will remove the event listener. useEffect will call this function when the component unmounts
    return
 appleAuth
.
onCredentialRevoked
(
async
 (
)
 =>
 {
      console
.
warn
(
'If this function executes, User Credentials have been Revoked'
)
;
    }
)
;
  }
,
 [
]
)
;
 // passing in an empty array as the second argument ensures this is only ran once when component mounts initially.

  return
 (
    <
View
>
      <
AppleButton
 onPress
=
{
(
)
 =>
 onAppleButtonPress
(
)
}
 /
>
    <
/
View
>
  )
;
}

4. Implement the logout process

There is an operation appleAuth.Operation.LOGOUT, however it does not work as expected and is not even being used by Apple in their example code. See this issue for more information

So it is recommended when logging out to just clear all data you have from a user, collected during appleAuth.Operation.LOGIN.

Android

1. Initial set-up

Make sure to correctly configure your Apple developer account to allow for proper authentication on Android. You can checkout our guide for more info.

// App.js

import
 React
 from
 'react'
;
import
 {
 View
 }
 from
 'react-native'
;
import
 {
 appleAuthAndroid
,
 AppleButton
 }
 from
 '@invertase/react-native-apple-authentication'
;

async
 function
 onAppleButtonPress
(
)
 {
}

// Apple authentication requires API 19+, so we check before showing the login button
function
 App
(
)
 {
  return
 (
    <
View
>
      {
appleAuthAndroid
.
isSupported
 &&
 (
        <
AppleButton
          buttonStyle
=
{
AppleButton
.
Style
.
WHITE
}
          buttonType
=
{
AppleButton
.
Type
.
SIGN_IN
}
          onPress
=
{
(
)
 =>
 onAppleButtonPress
(
)
}
        /
>
      )
}
    <
/
View
>
  )
;
}

2. Implement the login process

// App.js

import

{

appleAuthAndroid

}

from

'@invertase/react-native-apple-authentication'

;

import

'react-native-get-random-values'

;

import

{

uuid

}

from

'uuid'

async

function

onAppleButtonPress

(

)

{

// Generate secure, random values for state and nonce

const

rawNonce

uuid

(

)

;

const

state

uuid

(

)

;

// Configure the request

appleAuthAndroid

configure

(

{

// The Service ID you registered with Apple

clientId

'com.example.client-android'

// Return URL added to your Apple dev console. We intercept this redirect, but it must still match

// the URL you provided to Apple. It can be an empty route on your backend as it's never called.

redirectUri

'https://example.com/auth/callback'

// The type of response requested - code, id_token, or both.

responseType

appleAuthAndroid

ResponseType

ALL

// The amount of user information requested from Apple.

scope

appleAuthAndroid

Scope

ALL

// Random nonce value that will be SHA256 hashed before sending to Apple.

nonce

rawNonce

// Unique state value used to prevent CSRF attacks. A UUID will be generated if nothing is provided.

state

}

)

;

// Open the browser window for user sign in

const

response

await

appleAuthAndroid

signIn

(

)

;

// Send the authorization code to your backend for verification

}

MacOS

This library works on MacOS 10.15+ if using in conjunction with react-native-macos.

Web (not react-native-web, but that may come as a follow-on, this is pure web at the moment)

1. Initial set-up

Ensure you follow the android steps above.
Install the web counterpart yarn add react-apple-signin-auth in your web project.

2. Implement the login process on web

import
 AppleSignin
 from
 'react-apple-signin-auth'
;

/** Apple Signin button */
const
 MyAppleSigninButton
 =
 (
{
 ...rest
 }
)
 =>
 (
  <
AppleSignin
    /** Auth options passed to AppleID.auth.init() */
    authOptions
=
{
{
      clientId
: 'SAME AS ANDROID'
,
      redirectURI
: 'SAME AS ANDROID'
,
      scope
: 'email name'
,
      state
: 'state'
,
      /** sha256 nonce before sending to apple to unify with native firebase behavior - https://github.com/invertase/react-native-apple-authentication/issues/28 */
      nonce
: sha256
(
'nonce'
)
,
      /** We have to usePopup since we need clientSide authentication */
      usePopup
: true
,
    }
}
    onSuccess
=
{
(
response
)
 =>
 {
      console
.
log
(
response
)
;
      // {
      //     "authorization": {
      //       "state": "[STATE]",
      //       "code": "[CODE]",
      //       "id_token": "[ID_TOKEN]"
      //     },
      //     "user": {
      //       "email": "[EMAIL]",
      //       "name": {
      //         "firstName": "[FIRST_NAME]",
      //         "lastName": "[LAST_NAME]"
      //       }
      //     }
      // }
    }
}
  /
>
)
;

export
 default
 MyAppleSigninButton
;

3. Verify serverside

Send the apple response to your server.
See Serverside Verification
Ensure that you pass the clientID as the web service ID, not the native app bundle. Since the project utilizes the service ID for authenticating web and android.

Serverside verification

Nonce

Based on the Firebase implementation guidelines the nonce provided to appleAuth.performRequest (iOS) and appleAuthAndroid.configure (Android) is automatically SHA256-hashed.
To verify the nonce serverside you first need to hash the nonce value, ie:
```
crypto
.
createHash
(
'sha256'
)
.
update
(
nonce
)
.
digest
(
'hex'
)
;
```

The nonce can then be easily compared serverside for extra security verification, ie:

import
 crypto
 from
 'crypto'
;
import
 appleSigninAuth
 from
 'apple-signin-auth'
;

appleIdTokenClaims
 =
 await
 appleSigninAuth
.
verifyIdToken
(
id_token
,
 {
  /** sha256 hex hash of raw nonce */
  nonce
: nonce
 ? crypto
.
createHash
(
'sha256'
)
.
update
(
nonce
)
.
digest
(
'hex'
)
 : undefined
,
}
)
;

FAQs

Why does full name and email return null?
- Apple only returns the full name and email on the first login, it will return null on the succeeding login so you need to save those data.
- Apple APIs appear to be sensitive to the order you place the scopes in the auth request. Place first name first, like this:
```
 const
 appleAuthRequestResponse
 =
 await
 appleAuth
.
performRequest
(
{
   requestedOperation
: appleAuth
.
Operation
.
LOGIN
,
   requestedScopes
: [
appleAuth
.
Scope
.
FULL_NAME
,
 appleAuth
.
Scope
.
EMAIL
]
,
 }
)
;
```
- For testing purposes, to be receive these again, go to your device settings; Settings > Apple ID, iCloud, iTunes & App Store > Password & Security > Apps Using Your Apple ID, tap on your app and tap Stop Using Apple ID. You can now sign-in again and you’ll receive the full name and `email.
- Keep in mind you can always access the email property server-side by inspecting the id_token returned from Apple when verifying the user.
How to change button language? (iOS)
- Native Apple Button component reads language value from CFBundleDevelopmentRegion at Info.plist file. By changing CFBundleDevelopmentRegion value you can change default language for component.
```
<key
>CFBundleDevelopmentRegion</key>
<string
>en</string
>
```
- For supporting multi language, you can add CFBundleAllowMixedLocalizations key to Info.plist.
```
<key
>CFBundleAllowMixedLocalizations</key>
<string
>true</string
>
```

How do I get the email after the first login?

You can get the email address by parsing the JWT token that’s returned from any authentication, like so:

import
 {
 appleAuth
 }
 from
 '@invertase/react-native-apple-authentication'
;
import
 jwt_decode
 from
 'jwt-decode'
;

const
 appleAuthRequestResponse
 =
 await
 appleAuth
.
performRequest
(
{
  requestedOperation
: appleAuth
.
Operation
.
LOGIN
,
  requestedScopes
: [
appleAuth
.
Scope
.
EMAIL
,
 appleAuth
.
Scope
.
FULL_NAME
]
}
)
;
// other fields are available, but full name is not
const
 {
 email,
 email_verified,
 is_private_email,
 sub }
 =
 jwt_decode
(
appleAuthRequestResponse
.
identityToken
)

Troubleshooting

The operation couldn’t be completed. (com.apple.AuthenticationServices.AuthorizationError error 1000.)

Case 1:

Check that the connection settings have been made correctly.
The setup can be found here: Initial Setup

Case 2:

If you are using the function getCredentialStateForUser on a simulator, this error will always be triggered, for the reason that this function verifies the authenticity of the device.

You must test your code on a real device.

Case 3:

If you are using a simulator, go to Manage Apple Account.

Search for “Devices”, select “Simulator” and press “Remove from Account”.

show-devices

remove-from-manager

It should work fine.

"invalid_client" in Android webview

Make sure to read the Android services setup docs.

Case 1:

The clientId you passed to appleAuthAndroid.configure doesn’t match the Service ID you setup in your Apple developer console.

Case 2:

Your Service ID is attached to the wrong Primary App ID, and therefore uses the incorrect Sign In with Apple key.

Case 3:

The redirectUri you passed to appleAuthAndroid.configure doesn’t match one of the return URLs or domains/subdomains you added in your Apple developer console. The URL must match exactly, and cannot contain a query string.
