# Enterprise SSO

Canonical expansion of the \~87-word stub. Setup steps live on [Integrations](https://docs.notionapps.com/integrations/integrations) so this page does not become a second Auth0/Okta manual.

## What this is / when to use it

Enterprise SSO means end users sign in with **your** Auth0 or Okta tenant (and, on some accounts, other SAML/OIDC arrangements support enables). NotionApps does not host the IdP.

Use it when IT requires a company tenant. Do not use it for a simple client portal — Email OTP or Email & password is enough.

## Before you start

The plan includes Auth0/Okta. You can create a Regular Web Application (Auth0) or OIDC app (Okta). You have every published hostname.

## Build it

Follow [Integrations](https://docs.notionapps.com/integrations/integrations#auth0) or [Okta](https://docs.notionapps.com/integrations/integrations#okta). Then enable the Users additional-auth toggle. Publish. Test a user who exists in the IdP **and** in the Users database (or signup).

## Every control

Domain / Client ID / Secret / Auth server ID / callbacks — on Integrations. Additional auth toggle — on Users. No separate SSO pane.

## What users see

A **Sign in with Auth0** or **Sign in with Okta** button next to the primary method.

## Limits and plans

Higher-plan. Callbacks must include every custom domain or login fails only on that host. Identity dual-write still applies ([Identity admin](https://docs.notionapps.com/users/identity-admin)).

## Example

Staff app: primary Email & password off, Okta only, signup off, Users provisioned from IT. Clients stay on a different app with Email OTP.

## Fix problems

Wrong callback, expired secret, or user not in the Users database. Rotate the secret in the same labeled field. Do not use Advanced JSON.
