Tutorial: How to Integrate Passkeys into Angular

Implementing Passkey Authentication in Angular with TypeScript

In this guide, we’ll walk through the process of integrating passkey authentication into an Angular application using TypeScript. Passkeys provide a secure and scalable way to manage user authentication, removing the need for traditional passwords.

View full tutorial in our original blog post here

Prerequisites

Before starting, ensure you’re familiar with Angular, HTML, CSS, and TypeScript. Additionally, make sure you have Node.js and NPM installed on your machine. Installing the Angular CLI is recommended for this tutorial:

npm install -g @angular/cli
Enter fullscreen mode Exit fullscreen mode

Setting Up the Angular Project

First, let’s create a new Angular project. In this example, we’re using Angular version 15.2.9:

ng new passkeys-demo-angular
Enter fullscreen mode Exit fullscreen mode

During setup, choose the following options:

  • Share pseudonymous usage data: No
  • Angular routing: Yes
  • Stylesheet format: CSS
  • Enable SSR: No (Choose Yes if your application requires server-side rendering)

Once the setup is complete, run the application to ensure everything is functioning:

ng serve
Enter fullscreen mode Exit fullscreen mode

Integrating Corbado for Passkey Authentication

1. Set Up Your Corbado Account

To start, create an account on the Corbado developer panel. This step allows you to experience passkey signup firsthand. After registering, create a project within Corbado by selecting “Corbado Complete” as your product. Specify “Web app” as the application type, and for the framework, select Angular. In your application settings, use the following details:

  • Application URL: http://localhost:4200
  • Relying Party ID: localhost

2. Embedding the Corbado UI Component

Next, you’ll need to install the required packages for Corbado integration. Navigate to your project’s root directory and install the necessary packages:

npm i @corbado/web-js
npm i -D @corbado/types @types/react @types/ua-parser-js
Enter fullscreen mode Exit fullscreen mode

Modify the app.component.ts to initialize Corbado when the application starts:

import { Component, OnInit } from '@angular/core';
import Corbado from "@corbado/web-js";

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
    title = 'passkeys-demo-angular';
    isInitialized = false;

    constructor() {
    }

    ngOnInit(): void {
        this.initialize();
    }

    async initialize() {
        try {
            await Corbado.load({
                projectId: "<Your Corbado Project ID>",
                darkMode: 'off'
            });
            this.isInitialized = true;
        } catch (error) {
            console.error('Initialization failed:', error);
        }
    }
}
Enter fullscreen mode Exit fullscreen mode

3. Creating Login and Profile Components

Generate two components: one for displaying the passkey login UI and another for showing basic user information upon successful authentication:

ng generate component login
ng generate component profile
Enter fullscreen mode Exit fullscreen mode

Update your app-routing.module.ts to define routes for the login and profile components:

// src/app/app-routing.module.ts

import { NgModule } from '@angular/core';
import { ProfileComponent } from "./profile/profile.component";
import { RouterModule, Routes } from "@angular/router";
import { LoginComponent } from "./login/login.component";

const routes: Routes = [
    { path: 'profile', component: ProfileComponent },
    { path: 'login', component: LoginComponent },
    { path: '', component: LoginComponent },
    { path: '**', redirectTo: '/' }
]

@NgModule({
    imports: [
        RouterModule.forRoot(routes)
    ],
    exports: [RouterModule]
})
export class AppRoutingModule {
}
Enter fullscreen mode Exit fullscreen mode

In login.component.ts, set up the passkey authentication UI and define the behavior after a successful login:

import { Component, OnInit, ViewChild, ElementRef, AfterViewInit } from '@angular/core';
import { Router } from '@angular/router';
import Corbado from "@corbado/web-js";

@Component({
    selector: 'app-login',
    templateUrl: './login.component.html',
    styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit, AfterViewInit {
    @ViewChild('authElement', { static: false }) authElement!: ElementRef;  // Access the element

    constructor(private router: Router) {
    }

    ngOnInit() {
        if (Corbado.user) {
            this.router.navigate(['/profile']);
        }
    }

    ngAfterViewInit() {
        // Mount the Corbado auth UI after the view initializes
        Corbado.mountAuthUI(this.authElement.nativeElement, {
            onLoggedIn: () => this.router.navigate(['/profile']), // Use Angular's router instead of window.location
        });
    }
}
Enter fullscreen mode Exit fullscreen mode

And in the login.component.html, add the following:

<div #authElement></div>
Enter fullscreen mode Exit fullscreen mode

4. Setting Up the Profile Page

The profile page will display basic user information (user ID and email) and provide a logout button. If the user isn’t logged in, the page will prompt them to return to the home page:

import { Component } from '@angular/core';
import { Router } from "@angular/router";
import Corbado from "@corbado/web-js";

@Component({
    selector: 'app-profile',
    templateUrl: './profile.component.html',
    styleUrls: ['./profile.component.css']
})
export class ProfileComponent {
    user = Corbado.user

    constructor(private router: Router) {
    }

    async handleLogout() {
        await Corbado.logout()
        await this.router.navigate(['/']);
    }
}
Enter fullscreen mode Exit fullscreen mode

In profile.component.html, conditionally render the user’s information based on their authentication state:

<div>
    <ng-container *ngIf="user; else notLoggedIn">
        <div>
            <h1>Profile Page</h1>
            <div>
                <p>
                    User-ID: {{user.sub}}
                    <br />
                    Email: {{user.email}}
                </p>
            </div>
            <button (click)="handleLogout()">Logout</button>
        </div>
    </ng-container>

    <ng-template #notLoggedIn>
        <div>
            <p>You're not logged in.</p>
            <p>Please go back to <a routerLink="/">home</a> to log in.</p>
        </div>
    </ng-template>
</div>
Enter fullscreen mode Exit fullscreen mode

Running the Application

Once everything is set up, run the application:

ng serve
Enter fullscreen mode Exit fullscreen mode

Visit http://localhost:4200 to view the login screen, and after successful authentication, you will be redirected to the profile page.
