This is a generic OAuth 2 client plugin. It let you configure the oauth parameters yourself instead of using SDKs. Therefore it is usable with various providers. See identity providers the community has already used this plugin with.
For Capacitor v4
npm i @byteowls/capacitor-oauth2
npx cap syncFor Capacitor v3 use 3.0.1
npm i @byteowls/capacitor-oauth2@3.0.1
npx cap syncFor Capacitor v2 use 2.1.0
npm i @byteowls/capacitor-oauth2@2.1.0

See the excellent article about OAuth2 response type combinations.
https://medium.com/@darutk/diagrams-of-all-the-openid-connect-flows-6968e3990660
The plugin on the other will behave differently depending on the existence of certain config parameters:
These parameters are:
accessTokenEndpointresourceUrl
e.g.
If responseType=code, pkceDisable=true and accessTokenEndpoint is missing the authorizationCode will be resolve along with the whole authorization response.
This only works for the Web and Android. On iOS the used lib does not allows to cancel after the authorization request see #13.
If you just need the id_token JWT you have to set accessTokenEndpoint and resourceUrl to null.
These flows are already working and were tested by me.
responseType: "token"
...
responseType: "code"
pkceEnable: true
...
Please be aware that some providers (OneDrive, Auth0) allow Code Flow + PKCE only for native apps. Web apps have to use implicit flow.
For security reasons this plugin does/will not support Code Flow without PKCE.
That would include storing your client secret in client code which is highly insecure and not recommended. That flow should only be used on the backend (server).
Starting with version 3.0.0, the plugin is registered automatically on all platforms.

This implementation just opens a browser window to let users enter their credentials.
As there is no provider SDK used to accomplish OAuth, no additional javascript files must be loaded and so there is no performance impact using this plugin in a web application.
On Web/PWA the plugin is registered automatically by Capacitor.
Prerequisite: Capacitor Android Docs
On Android the plugin is registered automatically by Capacitor.
Skip this, if you use a OAuth2CustomHandler
The AndroidManifest.xml in your Capacitor Android project already contains
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="@string/custom_url_scheme" />
</intent-filter>Find the following line in your AndroidManifest.xml
<data android:scheme="@string/custom_url_scheme" />and change it to
<data android:scheme="@string/custom_url_scheme" android:host="oauth" />Note: Actually any value for android:host will do. It does not has to be oauth.
This will fix an issues within the oauth workflow when the application is shown twice. See Issue #15 for details what happens.
In your strings.xml change the custom_url_scheme string to your actual scheme value. Do NOT include ://oauth/redirect or other endpoint urls here!
<string name="custom_url_scheme">com.example.yourapp</string>
<!-- wrong -->
<!-- <string name="custom_url_scheme">com.example.yourapp://endpoint/path</string> -->android.defaultConfig.manifestPlaceholders = [
// change to the 'custom_url_scheme' value in your strings.xml. They need to be the same. e.g.
"appAuthRedirectScheme": "com.example.yourapp"
]Troubleshooting
- If your
appAuthRedirectSchemedoes not get recognized because you are using a library that replaces it (e.g.: onesignal-cordova-plugin), you will have to add it to yourbuildTypeslike the following:
android.buildTypes.debug.manifestPlaceholders = [
'appAuthRedirectScheme': '<@string/custom_url_scheme from string.xml>' // e.g. com.companyname.appname
]
android.buildTypes.release.manifestPlaceholders = [
'appAuthRedirectScheme': '<@string/custom_url_scheme from string.xml>' // e.g. com.companyname.appname
]- "ERR_ANDROID_RESULT_NULL": See Issue #52 for details. I cannot reproduce this behaviour. Moreover there might be situation this state is valid. In other cases e.g. in the linked issue a configuration tweak fixed it.
Some OAuth provider (Facebook) force developers to use their SDK on Android.
This plugin should be as generic as possible so I don't want to include provider specific dependencies.
Therefore I created a mechanism which let developers integrate custom SDK features in this plugin.
Simply configure a full qualified classname in the option property android.customHandlerClass.
This class has to implement com.byteowls.capacitor.oauth2.handler.OAuth2CustomHandler.
See a full working example below!
On iOS the plugin is registered automatically by Capacitor.
Skip this, if you use a OAuth2CustomHandler
Open ios/App/App/Info.plist in XCode (Context menu -> Open as -> Source) and add the value of redirectUrl from your config without :/ like that
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>com.companyname.appname</string>
</array>
</dict>

- No timeline.
You can use the capacitor-secure-storage plugin for this.
This plugin stores data in secure locations for natives devices.
- For Android, it will store data in a
AndroidKeyStoreand aSharedPreferences. - For iOS, it will store data in a
SwiftKeychainWrapper.
These are some of the providers that can be configured with this plugin. I'm happy to add others ot the list, if you let me know.
| Name | Example (config,...) | Notes |
|---|---|---|
| see below | ||
| see below | ||
| Azure | see below | |
| Apple | see below | ios only |
Minimum config
appleLogin() {
OAuth2Client.authenticate({
appId: "xxxxxxxxx",
authorizationBaseUrl: "https://appleid.apple.com/auth/authorize",
});
}The plugin requires authorizationBaseUrl as it triggers the native support and because it is needed for other platforms anyway. Those platforms are not supported yet.
appId is required as well for internal, generic reasons and any not blank value is fine.
It is also possible to control the scope although Apple only supports email and/or fullName. Add siwaUseScope: true to the ios section.
Then you can use scope: "fullName", scope: "email" or both but the latter is the default one if siwaUseScope is not set or false.
appleLogin() {
OAuth2Client.authenticate({
appId: "xxxxxxxxx",
authorizationBaseUrl: "https://appleid.apple.com/auth/authorize",
ios: {
siwaUseScope: true,
scope: "fullName"
}
});
}As "Signin with Apple" is only supported since iOS 13 you should show the according button only in that case.
In Angular do sth like
import {Component, OnInit} from '@angular/core';
import {Device, DeviceInfo} from "@capacitor/device";
import {OAuth2Client} from "@byteowls/capacitor-oauth2";
@Component({
templateUrl: './siwa.component.html'
})
export class SiwaComponent implements OnInit {
ios: boolean;
siwaSupported: boolean;
deviceInfo: DeviceInfo;
async ngOnInit() {
this.deviceInfo = await Device.getInfo();
this.ios = this.deviceInfo.platform === "ios";
if (this.ios) {
const majorVersion: number = +this.deviceInfo.osVersion.split(".")[0];
this.siwaSupported = majorVersion >= 13;
}
}
}And show the button only if siwaSupported is true.
The response contains these fields:
"id"
"given_name"
"family_name"
"email"
"real_user_status"
"state"
"id_token"
"code"
not supported
not supported
not supported
It's important to use the urls you see in the Azure portal for the specific platform.
Note: Don't be confused by the fact that the Azure portal shows "Azure Active Directory" and "Azure AD B2C" services. They share the same core features and therefore the plugin should work either way.
import {OAuth2AuthenticateOptions, OAuth2Client} from "@byteowls/capacitor-oauth2";
export class AuthService {
getAzureB2cOAuth2Options(): OAuth2AuthenticateOptions {
return {
appId: environment.oauthAppId.azureBc2.appId,
authorizationBaseUrl: `https://login.microsoftonline.com/${environment.oauthAppId.azureBc2.tenantId}/oauth2/v2.0/authorize`,
scope: "https://graph.microsoft.com/User.Read", // See Azure Portal -> API permission
accessTokenEndpoint: `https://login.microsoftonline.com/${environment.oauthAppId.azureBc2.tenantId}/oauth2/v2.0/token`,
resourceUrl: "https://graph.microsoft.com/v1.0/me/",
responseType: "code",
pkceEnabled: true,
logsEnabled: true,
web: {
redirectUrl: environment.redirectUrl,
windowOptions: "height=600,left=0,top=0",
},
android: {
redirectUrl: "msauth://{package-name}/{url-encoded-signature-hash}" // See Azure Portal -> Authentication -> Android Configuration "Redirect URI"
},
ios: {
pkceEnabled: true, // workaround for bug #111
redirectUrl: "msauth.{package-name}://auth"
}
};
}
}If you need to use custom scopes configured in "API permissions" and created in "Expose an API" in Azure Portal you might need
to remove the resourceUrl parameter if your scopes are not included in the response. I can not give a clear advise on those Azure specifics.
Try to experiment with the config until Azure includes everything you need in the response.
A configuration with custom scopes might look like this:
import {OAuth2Client} from "@byteowls/capacitor-oauth2";
getAzureB2cOAuth2Options(): OAuth2AuthenticateOptions {
return {
appId: environment.oauthAppId.azureBc2.appId,
authorizationBaseUrl: `https://login.microsoftonline.com/${environment.oauthAppId.azureBc2.tenantId}/oauth2/v2.0/authorize`,
scope: "api://uuid-created-by-azure/scope.name1 api://uuid-created-by-azure/scope.name2", // See Azure Portal -> API permission / Expose an API
accessTokenEndpoint: `https://login.microsoftonline.com/${environment.oauthAppId.azureBc2.tenantId}/oauth2/v2.0/token`,
// no resourceURl!
responseType: "code",
pkceEnabled: true,
logsEnabled: true,
web: {
redirectUrl: environment.redirectUrl,
windowOptions: "height=600,left=0,top=0",
},
android: {
redirectUrl: "msauth://{package-name}/{url-encoded-signature-hash}" // See Azure Portal -> Authentication -> Android Configuration "Redirect URI"
},
ios: {
pkceEnabled: true, // workaround for bug #111
redirectUrl: "msauth.{package-name}://auth"
}
};
}

}If you have only Azure B2C as identity provider you have to add a new intent-filter to your main activity in AndroidManifest.xml.
<!-- azure ad b2c -->

</intent-filter>If you have multiple identity providers or your logins always ends in a USER_CANCELLED error like in #178
you have to create an additional Activity in AndroidManifest.xml.
These are both activities! Make sure to replace com.company.project.MainActivity with your real qualified class path!

Since October 2018 Strict Mode for Redirect Urls is always on.
Use Strict Mode for Redirect URIs
Only allow redirects that use the Facebook SDK or that exactly match the Valid OAuth Redirect URIs. Strongly recommended.
Before that it was able to use fb<your_app_id>:/authorize in a Android or iOS app and get the accessToken.
Unfortunately now we have to use the SDK for Facebook Login.
I don't want to have a dependency to facebook for users, who don't need Facebook OAuth.
To address this problem I created a integration with custom code in your app customHandlerClass
See https://developers.facebook.com/docs/facebook-login/android/ for more background on how to configure Facebook in your Android app.

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Initialize Facebook SDK
FacebookSdk.sdkInitialize(this.getApplicationContext());
callbackManager = CallbackManager.Factory.create();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (callbackManager.onActivityResult(requestCode, resultCode, data)) {
return;
}
}
public CallbackManager getCallbackManager() {
return callbackManager;
}

}This handler will be automatically discovered up by the plugin and handles the login using the Facebook SDK. See https://developers.facebook.com/docs/swift/login/#custom-login-button for details.
- The users that have redirect problem after success grant add the following code to
ios/App/App/AppDelegate.swift. This code correctly delegate the FB redirect url to be managed by Facebook SDK.
import UIKit
import FacebookCore
import FacebookLogin
import Capacitor
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
// other methods
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
// Called when the app was launched with a url. Feel free to add additional processing here,
// but if you want the App API to support tracking app url opens, make sure to keep this call
if let scheme = url.scheme, let host = url.host {
let appId: String = Settings.appID!
if scheme == "fb\(appId)" && host == "authorize" {
return ApplicationDelegate.shared.application(app, open: url, options: options)
}
}
return CAPBridge.handleOpenUrl(url, options)
}
// other methods
