We’re excited to announce that Multiple Custom Domains (MCD) is now Generally Available.

With Multiple Custom Domains, Enterprise customers can support multiple branded login experiences from a single Auth0 tenant. This helps you deliver more tailored authentication experiences across consumer applications, multi-brand businesses, and B2B SaaS use cases.

MCD GA includes support for:

  • Configuring custom domains at scale within a single tenant
  • A default domain for streamlined development and testing
  • Passkey enrollment on custom domains
  • B2B SaaS Self-Service SSO customizations
  • Custom domain metadata in Advanced Customizations for Universal Login (ACUL)
  • Support across Management SDKs, Authentication SDKs, and Forms
