## TL;DR

Use the deploy CLI or Terraform to stop config drift; do it by hand and the tenants WILL diverge. Watch: connection enablement is per-org; the organization parameter must be passed on every login; token validation must check org_id. Cost: N tenants to configure, monitor, and keep in sync. Simplest to operate; do not add Organizations ceremony you do not need.

## When to use

You are seeing this: Each customer is an Organization in a single tenant. Use this skill when you run into "One tenant per customer vs Organizations: pick the multi-tenant model".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Option A: Organizations (one tenant)

Each customer is an Organization in a single tenant. Shared connections or per-org connections, org_id in tokens, JIT membership for onboarding.

Choose when: standard B2B SaaS, customers want SSO with their IdP (enterprise connection per org), you want one codebase and one config to operate.

Watch: connection enablement is per-org; the organization parameter must be passed on every login; token validation must check org_id.

## Option B: Tenant per customer

Each customer gets their own Auth0 tenant.

Choose when: regulatory isolation (data residency per customer), customers demand their own Auth0 dashboard/admin boundary, or radically different auth config per customer that Organizations cannot express.

Cost: N tenants to configure, monitor, and keep in sync. Use the deploy CLI or Terraform to stop config drift; do it by hand and the tenants WILL diverge.

## Option C: Single tenant, no orgs

One shared user pool, application-level tenancy in your own data model.

Choose when: consumer app or simple B2B where customers do not need isolated login contexts or their own IdPs. Simplest to operate; do not add Organizations ceremony you do not need.

## Decision inputs

- Do customers bring their own IdP? Yes -> Organizations (or tenants).
- Data residency per customer? Yes -> tenants in the right regions.
- Team size for auth ops? Small -> fewer tenants, prefer Organizations.

## Checklist

- Decision written down with the reasons; it is expensive to reverse.
- If tenants: config-as-code from day one.
