A wrapper to make it really easy to deal with iOS Keychain and store your user’s credentials securely.

Key Features

  • Simple interface to store user’s credentials (e.g. JWT) in the Keychain.
  • Store credentials under an Access Group to enable Keychain Sharing.
  • Support for iOS 8 Access Control for fine grained access control.
  • TouchID and Keychain integration with iOS 8 new accessibility field kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly.


  • iOS 9.0+ / macOS 10.11+ / tvOS 9.0+ / watchOS 2.0+
  • Xcode 10.x
  • Swift 4.x/5.x



SimpleKeychain is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod "SimpleKeychain"


In your Cartfile add

github "auth0/SimpleKeychain"

Before Getting Started


Import Lock module in your swift file:

import SimpleKeychain


Save a JWT token or password

let jwt = //user's JWT token obtained after login
A0SimpleKeychain().setString(jwt, forKey:"auth0-user-jwt")

Obtain a JWT token or password

let jwt = A0SimpleKeychain().string(forKey: "auth0-user-jwt")

Share JWT Token with other apps using iOS Access Group

let jwt = //user's JWT token obtained after login
let keychain = A0SimpleKeychain(service: "Auth0", accessGroup: "")
keychain.setString(jwt, forKey:"auth0-user-jwt")

Store and retrieve JWT token using TouchID and Keychain AcessControl attribute (iOS 8 Only).

Let’s save the JWT first:

let jwt = //user's JWT token obtained after login
let keychain = A0SimpleKeychain()
keychain.useAccessControl = true
keychain.defaultAccessiblity = .whenPasscodeSetThisDeviceOnly
keychain.setString(jwt, forKey:"auth0-user-jwt")

If there is an existent value under the key auth0-user-jwt saved with AccessControl and A0SimpleKeychainItemAccessibleWhenPasscodeSetThisDeviceOnly, iOS will prompt the user to enter their passcode or fingerprint before updating the value.

Then let’s obtain the value

let message = NSLocalizedString("Please enter your passcode/fingerprint to login with awesome App!.", comment: "Prompt TouchID message")
let keychain = A0SimpleKeychain()
let jwt = keychain.string(forKey: "auth0-user-jwt", promptMessage:message)

Remove a JWT token or password

A0SimpleKeychain().deleteEntry(forKey: "auth0-user-jwt")


Just clone the repo, and run pod install from the Example directory and you’re ready to contribute!
