Hello Auth0 Community,

I’m developing a B2B SaaS application and considering upgrading from the Auth0 Free plan.

Before purchasing, I would like to clarify which subscription is required for Advanced Customizations for Universal Login (ACUL).

My dashboard currently shows Essentials ($35/month) and Professional ($240/month).

My questions are:

  1. Is ACUL available with Essentials, or does it require Professional or Enterprise?
  2. Does “Customize Signup & Login” on the pricing page include ACUL?
  3. Can ACUL support a single login interface with email/password, Google, and username/password authentication across two Database Connections?
  4. Can self-service signup be disabled for invited tenant employees while remaining available for regular customers?

I already have a verified Auth0 custom domain and two working Database Connections.

I’d appreciate clarification before upgrading. Thank you!
