Auth0 Universal Login

Introducing the New Universal Login Experience

Simplify your user experience with our new design, reimagined login flows, and quick-loading pages

June 19, 2019

Auth0's new Universal Login experience — including reimagined login flows, with a fresh UX design, and lightweight pages — is now generally available. Here is everything you need to know about this release.

First, What is Universal Login?

Universal Login authenticates users via a central authorization server. This contrasts with an embedded login flow, which relies on JavaScript libraries to perform authentication via cross-origin request. (You can find a more detailed explanation of universal vs. embedded login here.)

Universal Login benefits include:

  • Simplified user experience
  • Streamlined app integration
  • Improved administration
  • Increased authentication security, especially with 3rd party integrations and mobile apps

Why Are We Updating Universal Login?

The new Universal Login experience allows us to provide a smoother login experience for you and your users while simplifying the development of future capabilities. The classic Universal Login experience based on Lock remains available for customers who wish to use it.

What is New About the New Experience?

Here are the key improvements and additional capabilities available with the new Universal Login. We will be adding more over time:

Lightweight login pages

JavaScript is no longer required for login pages using the new Universal Login experience as the pages are rendered server-side. This drastically reduces the size of the page the end-user needs to load, resulting in lightweight pages that load quickly without consuming much bandwidth. In some cases, we see a nearly 80% reduction in page size from the classic Universal Login experience.

Redesigned flows for login, MFA, signup, and more

The fresh design for Universal Login pages and flows, combined with easy customization capabilities results in a unified, modern look and feel for your login pages. New flows can also be enabled in conjunction with existing classic Universal Login implementations. To see an interactive demonstration of the new flows visit

Verify Identity from Auth0 Login modal

Multiple authenticator support for multi-factor authentication

Customers can now enable support for multiple MFA authenticators. End users can now enable multiple MFA factors and then choose which one to use during the login process.

Other Login Methods View

Language localization

All of the flows are fully localized in English, Spanish, German, French, Portuguese, Dutch, Norwegian, Swedish, Danish, Finnish, Chinese, Russian, Italian, and Japanese. Language can be determined via browser settings, a parameter in the /authorize endpoint, or tenant settings.

Different Language Localization/Internationalization Login View

Email as an MFA factor

The ability to use a confirmed email address as a method for multi-factor authentication.

Auth0 Email MFA Verification

The consent flow now offers language localization, more branding customization options, and more descriptive text.

Authorize App/Consent View in  Login modal

Device Flow

Device Flow is an OAuth 2.0 authorization flow designed for devices that either don’t have access to a browser or have limited input capabilities. Device Flow enables end-users to authorize such devices to access APIs (protected resources) provided the devices have an internet connection.

Successful password reset and email verification redirect

Now when a user successfully completes a password reset or verifies their email address, they will be redirected to the default tenant or application login URL, allowing them to quickly begin the login flow.

What features are on the Universal Login Roadmap?

We have a number of improvements in the works. We can share some of our future capabilities, but not all. Here are just a few things that are currently planned:

Editable text

The new Universal Login text can be customized for your needs.

Enhanced customization

Even further customization and enhancements for the look and feel for the Universal Login pages to generate an exceptional login experience.

Home Realm Discovery

Specifically for customers with an enterprise identity provider. Home Realm Discovery will allow users to enter their email in the login screen, which will then automatically detect the connection they should be authenticated with.

What Are the Limitations to the New Universal Login Experience?

There are currently a few limitations to the new Universal Login experience. Visit docs for an up-to-date list of the limitations.
