Covers creating an Auth0 account and SPA application, installing the Auth0 Angular SDK, configuring callback URLs, enabling passkeys via the Auth0 dashboard, and setting up identifier-first login flow. Also explains the underlying WebAuthn registration and authentication ceremonies, the roles of relying party, client, and authenticator, and how resident (client-side discoverable) keys enable seamless login UX with autocomplete. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I add passkey authentication to an Angular app using Auth0? Install the Auth0 Angular SDK and configure provideAuth0 with your domain and client ID, then enable passkeys in the Auth0 dashboard under Database Connections > Authentication Methods, which requires enabling identifier-first login under Authentication Profile. No code changes are needed beyond the initial Auth0 SDK setup since passkey support is a zero-code dashboard configuration. _daily.dev surfaces guides like this for developers wiring passkey login into Angular apps._ ### What is the difference between resident keys and server-side discoverable passkeys? Resident keys (client-side discoverable passkeys) let the browser detect available passkeys for a domain locally, without the server needing to know which passkeys exist, enabling login by just clicking without entering an identifier. Server-side discoverable keys require the user to provide an identifier first so the server can determine which passkeys they own, which hurts login UX. _developers choosing a passkey UX approach can track authentication patterns like this on daily.dev._ ### What does the autocomplete="webauthn" HTML attribute do? Setting autocomplete="webauthn" on an email input field allows the browser to load any resident passkeys available for that domain and offer autocomplete suggestions during login. This attribute value must be exactly "webauthn" to work correctly across different browsers when implementing passkey-based sign-in flows. _daily.dev helps developers keep up with small but critical WebAuthn implementation details like this._ ## Similar posts on daily.dev - [How to Sign Up and Log In with Passkeys on iOS Using Auth0](https://daily.dev/posts/how-to-sign-up-and-log-in-with-passkeys-on-ios-using-auth0-xgavx7ekm) · Auth0 · 0 upvotes · 0 comments - [Using ASP.NET Core Passkeys for Second Factor Authentication](https://daily.dev/posts/using-asp-net-core-passkeys-for-second-factor-authentication-oh2mcwiop) · Maarten Balliauw · 0 upvotes · 0 comments - [Killing the Password: How to Add Passkeys to Your Rails 8 App](https://daily.dev/posts/killing-the-password-how-to-add-passkeys-to-your-rails-8-app-prvzndxhp) · Ruby Flow · 0 upvotes · 0 comments - [Biometrics authentication for your mobile app](https://daily.dev/posts/biometrics-authentication-for-your-mobile-app-knf7upt7m) · thoughbot · 2 upvotes · 0 comments --- Tags: [#authentication](https://daily.dev/tags/authentication), [#angular](https://daily.dev/tags/angular), [#auth0](https://daily.dev/tags/auth0), [#passkeys](https://daily.dev/tags/passkeys) [View this post on daily.dev](https://daily.dev/posts/biometric-authentication-in-angular-using-auth0-yokjshezt) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Biometric Authentication in Angular Using Auth0","url":"https://daily.dev/posts/biometric-authentication-in-angular-using-auth0-yokjshezt","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/biometric-authentication-in-angular-using-auth0-yokjshezt"},"datePublished":"2026-08-04T18:15:18.454Z","dateModified":"2026-09-14T08:35:07.511Z","description":"A step-by-step guide to integrating passkey-based biometric authentication into an Angular single-page application using the Auth0 SDK.
