At Auth0, we understand that no two customer identity stories are the same. Every company has a brand identity, a secret sauce, and a unique aesthetic vision. Today, we are very excited to introduce the next evolution in customization for Universal Login, Advanced Customizations for Universal Login (ACUL). ACUL enables your team to build custom, client-rendered versions of each Universal Login screen, allowing you to control every pixel of the Universal Login experience.

This Early Access release of ACUL is available to all paid customers. Public cloud customers can start using it today! Those on private cloud will be enabled as part of their regular release cycle. This initial EA release provides a new configuration API, CDT and SDK support, and allows you to build custom versions of the following screens:

  • Login
  • Login Id
  • Login Password
  • Login Passwordless Email Code
  • Login Passwordless SMS OTP
  • Signup
  • Signup Id
  • Signup Password
  • Passkey Enrollment
  • Passkey Enrollment Local
  • Phone Identifier Enrollment (used for identity verification during Signup)
  • Phone Identifier Challenge (used for identity verification during Signup)
  • Email Identifier Challenge (used for identity verification during Signup)
  • Interstitial Captcha
  • Reset Password
  • Reset Password Email
  • Reset Password Request
  • Reset Password Error
  • Reset Password Success

The following flows and capabilities are supported in ACUL EA:

  • Single step Signup & Login with password and social & enterprise connections
  • ID First Signup/Login using password, passwordless email/SMS OTP, passkeys, and social & enterprise connections
  • Basic Reset Password flow with and without Bot Detection
  • Flexible Identifiers with and without identity verification enabled during Signup
  • Bot detection with any of our 7 supported Captcha providers during the Signup, Login, and Reset Password flows
  • Capturing additional data during Signup and Login using custom prompts

This is just the beginning! In the coming months, we will be adding support for every screen and capability that Universal Login currently supports out of the box, a shiny new Dashboard UI for configuring ACUL, and lots more DX goodness!

Checkout our online documentation to learn more about ACUL and stay tuned to the Auth0 Changelog for updates and announcements!
