The fastest way to roll out custom logins

Auth0 Universal Login is a centralized authentication experience hosted by Auth0 that handles the entire login flow for your applications. By redirecting users to a more secure, Auth0-managed page, you verify that the highest security standards, such as phishing-resistant MFA and Passkeys, are automatically applied without needing to modify your application’s core codebase.

Auth0 Universal Login provides a centralized, hosted authentication page that handles the entire login lifecycle. Its features include native support for biometrics, social login, multi-factor authentication, custom logic, and custom branding, allowing developers to implement a more secure front door for their apps without writing complex frontend code.

Yes, Auth0 Universal Login is fully customizable via multiple implementation options. Through the Auth0 Dashboard, you can modify the theme, logos, and fonts to match your company’s brand, helping ensure that the transition from your application to the login screen is seamless and maintains user trust throughout the session. Additionally, through Auth0’s management API, developers can provide page templates using the Liquid template language for custom content and data capture support using HTML/CSS/JavaScript. For maximum flexibility and customization efforts, Auth0’s Advanced Customizations for Universal Login (ACUL) extends the capabilities of Universal Login to support multi-branding, complex security configurations, and integration of numerous analytics platforms.

Yes, Auth0 Universal Login supports custom domains. This allows you to host the login experience on a subdomain of your primary site (e.g., identity.yourbrand.com), verifying that the entire authentication journey remains within your trusted domain and provides a consistent brand experience.

Yes, Auth0 Universal Login features built-in internationalization (i18n) support. It can automatically detect a user’s browser language and display the login interface in about 80 supported languages, including right-to-left languages, providing a localized and accessible experience for a global customer base.

Yes, Auth0 Universal Login natively supports Passkeys, providing users with a phishing-resistant, biometric login experience. By enabling Passkeys, you allow users to sign in using FaceID or TouchID, which is significantly more secure than traditional passwords and offers a faster, more modern experience that today’s digital consumers expect.

Universal Login provides a unified interface for MFA, allowing users to choose their preferred factor, such as SMS, email, DUO security, biometrics via WebAuthN, or push notifications from the Auth0 Guardian app. This flexibility helps ensure that users can satisfy security requirements in the way that is most convenient for them, reducing friction without compromising on account protection.

Auth0 Universal Login makes it easy to add social login providers like Google, Facebook, and Apple with just a few clicks in the dashboard. These providers are automatically integrated into the hosted login page, offering your users a fast and familiar way to sign up and log in without creating a new password. Auth0 also supports custom OAuth2 connections for providers that are not available as one of the 74 pre-built connections in the Auth0 marketplace.

Universal Login improves security by centralizing the point of credential entry on a hardened, Auth0-managed domain. This mitigates the risk of cross-site scripting (XSS) and allows for the easy deployment of phishing-resistant factors like Passkeys and FIDO2-certified security keys across all your integrated apps.

Universal Login mitigates risks like cross-site scripting (XSS) by handling credential collection on a dedicated, hardened server. It also enables "Silent Authentication" and seamless SSO across multiple apps within your ecosystem, enabling a more secure and frictionless journey.

Universal Login and Embedded Login are two key ways to build conversion-friendly identity journeys. Many customers use a hybrid approach, using different solutions for different identity patterns.

Universal Login is Auth0’s hosted identity. It’s the fastest way to roll out secure-by-design identity flows with no-code and pro-code customization options. With Advanced Customization for Universal Login (ACUL), teams can control every pixel of the authentication experience using their own design system, tooling, and existing UI/UX investments—all on top of Auth0’s hosted authentication. Embedded Login is Auth0’s most flexible option. It lets you integrate identity flows into your application code using Auth0 APIs and SDKs for complete pro-code control. Blend authentication in-app, exactly where users convert. Use Auth0 configurable capabilities and built-in security tooling to reduce security roadblocks and custom code to scale faster.

Auth0 Actions allows you to execute custom Node.js code at specific triggers, like post-login or pre-registration. Use it to enrich user profiles, integrate with external APIs, or implement custom risk scoring without managing your own infrastructure. Additionally, Auth0 Forms extends Actions with a visual editor that allows developers to create customizable forms.
