Please refer to demo/index.htm for demo code

Note: WebAuthN registration is seemless, so login users will only need to confirm their emails the very first time only when they register with WebAuthN, but will have a more seamless experience the second time onwards.


npm install onz-auth --save


<script src="https://unpkg.com/onz-auth@1.0.26/dist/onz-auth-js-sdk.min.js"></script>


You'll need a CLIENT_ID, which you can get by creating a free account at OnzAuth.

WebAuthN can be enabled in the settings options after project creation. It is disabled by default.

import onz from "onz-auth"; // If using npm or included in script import

// Initialisation
const auth = new onz.Auth({
    clientID: 'Your Client ID', // Options
    containerID: 'myDiv', // Optional, defaults to 'container'
    isIframe: true, // Optional, defaults to 'false'

Sign in

Tokens will automatically be saved in localstorage with the following keys access_token, id_token, expiry, refresh_token after successful signin

auth.showLogin(); // Shows the login popup

Sign out

Tokens will automatically be cleared from localstorage after signing out

auth.logout(); // Signs out the current user

Events examples

// Authenticated event, after log in successful, contains accessToken, idToken, refreshToken, expiry
auth.on("authenticated", (authResult) => {
    console.log('authentication result', authResult);
    console.log('authentication access token', authResult.accessToken);

// Error message
auth.on("error", (errorMessage) => {
    console.error('authentication error', errorMessage);

// On popup or iframe closed
auth.on("closed", () => {
    console.log('iframe or popup is closed');
