Auth0 is an authentication broker that supports social identity providers as well as enterprise identity providers such as Active Directory, LDAP, Google Apps and Salesforce.

Lock-Twitter helps you integrate native Login with Twitter and Lock

Deprecation notice

This package relies on a token endpoint that is now considered deprecated. If your Auth0 client was created after Jun 8th 2017 you won't be able to use this package. This repository is left for reference purposes.

We recommend using browser-based flows to authenticate users. You can do that using the auth0.swift package, as explained in this document.



iOS 9+


The Lock-Twitter is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "Lock-Twitter", "~> 2.0"


Twitter authentication use Reverse Auth to obtain a valid access_token that can be sent to Auth0 Server and validate the user.

First create a new instance of A0TwitterAuthenticator

NSString *twitterApiKey = ...
A0TwitterAuthenticator *twitter = [A0TwitterAuthenticator newAuthenticationWithConsumerKey:twitterApiKey];
let twitterApiKey = ... //Remember to obfuscate your api key
let twitter = A0TwitterAuthenticator.newAuthentication(withConsumerKey: twitterApiKey)

and register it with your instance of A0Lock if native integration is available

A0Lock *lock = ... //Get your instance of A0Lock
if ([A0TwitterAuthenticator canUseNativeTwitterAuthentication]) {
    [lock registerAuthenticators:@[twitter]];
let lock = ... //Get your instance of A0Lock
if A0TwitterAuthenticator.canUseNativeTwitterAuthentication() {


For the case when there are more than one twitter account, Lock-Twitter will let the user choose one use an action sheet. Here are the keys you need to add to your Localizable.strings file

  • com.auth0.lock.integration.twitter.choose-account.title: Title when choosing from multiple accounts
  • com.auth0.lock.integration.twitter.choose-account.cancel: Cancel button title of the action sheet

Also when there are no accounts, Lock-Twitter will show an alert with an error that can be customizable with the following keys:

  • Title when no twitter account is found in the iOS device
  • Messsage when no twitter account is found in the iOS device




+ (BOOL)canUseNativeTwitterAuthentication;

Checks if it twitter native integration is available in the device.

BOOL canUse = [A0TwitterAuthenticator canUseNativeTwitterAuthentication];
let canUse = A0TwitterAuthenticator.canUseNativeTwitterAuthentication()


+ (A0TwitterAuthenticator *)newAuthenticatorWithConsumerKey:(NSString *)key;

Create a new 'A0TwitterAuthenticator' using a Twitter API key for the default twitter connection name.

A0TwitterAuthenticator *twitter = [A0TwitterAuthenticator newAuthenticatorWithConsumerKey:@"KEY"];
let twitter = A0TwitterAuthenticator.newAuthenticator(withConsumerKey: "KEY")


+ (A0TwitterAuthenticator *)newAuthenticatorWithConnectionName:(NSString *)connectionName consumerKey:(NSString *)consumerKey;

Create a new 'A0TwitterAuthenticator' using a Twitter API key and a connection name.

A0TwitterAuthenticator *twitter = [A0TwitterAuthenticator newAuthenticatorWithConnectionName:@"my-twitter" consumerKey:@"KEY"];
let twitter = A0TwitterAuthenticator.newAuthenticator(withConnectionName: "my-twitter", consumerKey: "KEY")
