Lock iOS: TouchID Authentication

Lock provides passwordless authentication with TouchID for your Auth0 DB connection. To start authenticating your users with TouchID please follow those steps:

  1. Add TouchID subspec module of Lock to your Podfile
pod 'Lock/TouchID'
  1. Import Lock's umbrella header
#import <Lock/Lock.h>

If your are coding in Swift, you need to import the header in your app's Bridging Header

  1. Instantiate A0TouchIDLockViewController and register authentication callback
A0TouchIDLockViewController *controller = [[A0TouchIDLockViewController alloc] init];
controller.onAuthenticationBlock = ^(A0UserProfile *profile, A0Token *token) {
    //Store token & profile. For example in the keychain using SimpleKeychain.
    [self dismissViewControllerAnimated:YES completion:nil];
let lock = A0Lock.shared()
let controller: A0TouchIDLockViewController = lock.newTouchIDViewController()
controller.onAuthenticationBlock = { (profile, token) in
    // Do something with token & profile. e.g.: save them.
    // Lock will not save the Token and the profile for you.
    // And dismiss the UIViewController.
    self.dismiss(animated: true, completion: nil)
  1. Present A0TouchIDLockViewController as the root controller of a UINavigationController
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    navController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:navController animated:YES completion:nil];
let navController = UINavigationController(rootViewController: controller)
if UIDevice.current.userInterfaceIdiom == .pad {
    navController.modalPresentationStyle = .FormSheet
self.presentViewController(navController, animated: true, completion:nil)

It's mandatory to present A0TouchIDLockViewController embedded in a UINavigationController.

And you'll see TouchID login screen
