A cordova plugin adding the iOS TouchID / Android fingerprint to your app and allowing you to store a password securely in the device keychain.


Automatically (CLI / Plugman)

Compatible with Cordova Plugman, compatible with PhoneGap 3.0 CLI, here's how it works with the CLI (backup your project first!):
From npm:
$ cordova plugin add cordova-plugin-keychain-touch-id
$ cordova prepare

The latest, from the master repo:
$ cordova plugin add
$ cordova prepare

touchid.js is brought in automatically. There is no need to change or add anything in your html.


1\. Add the following xml to your config.xml in the root directory of your www folder:
<feature name="TouchID">
  <param name="ios-package" value="TouchID" />

You'll need to add the LocalAuthentication.framework and Security.framework to your project. Click your project, Build Phases, Link Binary With Libraries, search for and add the frameworks.
2\. Grab a copy of TouchID.js, add it to your project and reference it in index.html:
<script type="text/javascript" src="js/touchid.js"></script>

3\. Download the source files and copy them to your project.
iOS: Copy the four .h and two .m files to platforms/ios/<ProjectName>/Plugins

Cordova plugin for interacting with iOS touchId and keychain
Make sure you check if the plugin is installed
if (window.plugins.touchid) {


Call the function you like
isAvailable(successCallback, errorCallback(msg)) will Check if touchid is available on the used device save(key,password, successCallback, errorCallback(msg)) will save a password under the key in the device keychain, which can be retrieved using a fingerprint
verify(key,message,successCallback(password), errorCallback(errorCode)) will open the fingerprint dialog, for the given key, showing an additional message. successCallback will return the password stored in key chain. errorCallback will return the error code, where -1 indicated not available.
has(key,successCallback, errorCallback) will check if there is a password stored within the keychain for the given key
delete(key,successCallback, errorCallback) will delete the password stored under given key from the keychain

Android quirks

When a new fingerprint is enrolled, no more fingerprints are enrolled, secure lock screen is disabled or forcibly reset, the key which is used to hash the password is permanently invalidated. It cannot be used anymore.
verify and save functions will return the "KeyPermanentlyInvalidatedException" message in the error callback. This invalid key is removed - user needs to save their password again.
if (window.plugins) {
    window.plugins.touchid.isAvailable(function() {
        window.plugins.touchid.has("MyKey", function() {
            alert("Touch ID avaialble and Password key available");
        }, function() {
            alert("Touch ID available but no Password Key available");
    }, function(msg) {
        alert("no Touch ID available");

if (window.plugins) {
    window.plugins.touchid.verify("MyKey", "My Message", function(password) {
        alert("Tocuh " + password);

if (window.plugins) {"MyKey", "My Password", function() {
        alert("Password saved");

if (window.plugins) {
    window.plugins.touchid.delete("MyKey", function() {
        alert("Password key deleted");
