June 25 Auth0 Community Ask Me Anything: Multiple Custom Domains

Community News Community AMA Series
1

We’re excited to invite you to our next online Auth0 Community Ask Me Anything (AMA) on June 25, 2025 with Pawan Bhardwaj, Principal Product Manager where we will dive into Multiple Custom Domains (MCD).

This is your opportunity to learn how MCD lets you serve multiple brand identities from a single Auth0 tenant, supporting tailored login experiences, branded email templates, and more. Whether you manage several B2C brands or offer white-labeled solutions for SaaS clients, this feature helps deliver consistent branding and seamless user experiences without the need for multiple tenants.

We’re currently in beta and gearing up to expand availability through Early Access. If you’re exploring MCD or thinking about how it might fit into your architecture, we’d love to hear from you. Your questions and feedback will help shape how we support and evolve this capability.

The problem I have is that I have another domain that I need to talk to our backend server and also need to use the passwordless login option. How can I enable the second custom domain to talk to the same resource backend and not trigger popup blockers.
