The Problem

Auth0 Is Live, but Nobody Wants to Touch the Tenant

It shows up when a staging test locks out real users, a migration forces every customer to reset a password, or an enterprise buyer asks for SAML.

  1. Shared tenant

    Development and production share one Auth0 tenant.

    Shared tenant

    Separate tenants built from the same repo and promoted through code review.

  2. Old Rules

    Token logic sits in Rules and Hooks that Auth0 is retiring.

    Old Rules

    Actions rewritten and tested against every app that reads those claims.

  3. Stuck users

    Half your customers still live in the old user table.

    Stuck users

    Lazy or bulk migration that keeps supported password hashes.

  4. Enterprise SSO

    A prospect wants SAML through their own Okta.

    Enterprise SSO

    Organizations with per-customer SAML or OIDC connections and self-serve setup.

Someone set up Auth0 in a weekend two years ago. Development and production share one tenant, so testing a login change means testing on real customers. The rules that add roles to tokens use a format Auth0 is retiring, and nobody knows which app depends on them. Your old user table still holds half your customers. Now an enterprise prospect wants SAML through their Okta, and every change feels like it could lock everyone out.

We start by splitting your tenants and putting every setting in a repo, so changes go through review. Old Rules and Hooks become Actions, existing users migrate with their passwords where the hash format allows, and each app gets Auth0's SDK for its framework. Business customers get Organizations with their own SAML or OIDC connection. Login changes ship like code, not like a dare.

  • Tenants managed as code

    Development and production tenants built from one repo, so every change is reviewed first.

  • Migration without mass resets

    Users move over through lazy migration or a bulk import that keeps supported password hashes.

  • Enterprise customers onboarded

    Organizations give each business customer its own SAML or OIDC connection and roles.

Our Auth0 Implementation Services Process

From Tenant Review to Production Login in Five Clear Steps

You approve the tenant design, the migration path, and each login flow, and you test every change in development before your customers see it.

  1. We look at your apps, your current user database, and who signs in: consumers, business customers, or both. You get an Auth0 plan per app, a monthly active user estimate, and a migration path. If a simpler login library covers you, we'll tell you before we quote.

What's Included

What You Get With an Auth0 SSO Setup

Auth0 tenants built as code, Universal Login on your domain, Actions, user migration, SSO across your apps, and Organizations with enterprise connections for business customers.

  • Tenants per environment

    Separate development and production tenants, configured from one repo with the Deploy CLI or Terraform.

  • Universal Login on your domain

    Auth0's hosted login page with your branding, custom domain, MFA, and the connections each app needs.

  • Actions for roles and claims

    Actions that add roles and custom claims to tokens, replacing any Rules or Hooks you still run.

  • User migration

    Lazy migration through a custom database connection, or a bulk import that keeps supported password hashes.

  • SSO across your apps

    One Auth0 session shared by your web apps, so customers sign in once and move between them.

  • Organizations and enterprise SSO

    Per-customer SAML or OIDC connections, invitations, and roles, with self service SSO links for customer IT teams.

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have built platforms, apps, and websites for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why Engineering Teams Trust Us With Auth0

Auth0 implementation services touch every customer login, so we test each change in a separate tenant before it reaches production.

  • Changes go through review

    Every tenant setting lives in your repo and ships through pull requests. Nobody edits production login rules in the dashboard on a Friday.

  • Test tenant first

    Every Action, connection, and branding change runs in your development tenant before production. Your real customers aren't the test group for a login change.

  • Passwords kept where possible

    We read your current hash format before planning the migration. Supported hashes move over, so customers keep signing in with what they know.

  • Active users watched

    Auth0 prices by monthly active users. We show you how your login design affects that count before you commit to a plan.

  • Off retiring features

    Rules and Hooks are deprecated in favor of Actions. We move your logic over now, so a future removal date can't break sign-in.

  • No lock-in to us

    Your tenants, repo, and runbook stay yours after handover. Any developer who knows Auth0 can pick up where we left off.

Overview

Good fit

  • SaaS teams starting on Auth0

    You chose Auth0 to avoid writing login code, and you want tenants, connections, and Actions set up properly before your first 1,000 users arrive.

  • Teams with a messy Auth0 tenant

    Your Auth0 implementation grew by hand, development shares a tenant with production, and old Rules still add the roles every API checks.

  • Products moving off homegrown login

    You're replacing your own password table with Auth0 and need existing customers to keep signing in without a forced reset email.

  • B2B SaaS facing enterprise buyers

    Your enterprise prospects want an Auth0 SAML integration with their own identity provider, set up by their IT team instead of yours.

  • Django and Python teams

    Your Django app needs Auth0 login, and you want the Authlib setup, sessions, and role checks done once and documented.

Not a fit

  • Staff access to company apps

    You want your own employees signing in to internal tools through Okta. Our Okta integration services cover that workforce access.

  • SSO built into your code

    You'd rather own SAML and OIDC in your codebase with no per-user fees. Our SSO integration services build it on your servers.

  • Sign in with Google only

    You only need Google or Apple sign-in buttons on one site. Our social login integration service covers that for less.

  • Budget under $900

    Your budget is under $900 and one app needs basic login. Auth0's own quickstart for your framework may be enough to start.

FAQ

Frequently Asked Questions

Straight answers on Auth0 SSO, Django, SAML, user migration, self-service SSO, retired Rules, and cost.

  • Auth0 SSO is single sign-on handled by Auth0: a customer signs in once and reaches every app connected to the same tenant. Auth0 keeps one session on its own domain with a browser cookie, so other apps skip the login screen. It also covers Auth0 SSO integrations with business customers, who sign in through their own identity provider.

  • You integrate with Auth0 by registering your app in an Auth0 tenant, adding the SDK for your framework, and sending users to Universal Login. Auth0 returns tokens after sign-in, and your app reads each user's roles from them. A solid Auth0 integration also keeps development and production tenants apart, with settings in code.

  • Auth0 implementation starts at $900 at DeveloperLook for one app on Universal Login with social connections, MFA, and separate tenants. The $2,400 plan adds SSO across 3 apps, Actions, user migration, and a custom domain. The $4,950 plan adds Organizations, enterprise connections, and self-service setup. Auth0's own plan, priced by monthly active users, is separate.

  • An Auth0 SSO setup takes 1 to 2 weeks for one app. Migrating existing users or adding Organizations stretches it to 3 to 6 weeks. Migration planning takes longest, because we test real password hashes before switching anyone. Promoting tenant settings through code keeps launch day short.

  • You integrate Auth0 with Django through the Authlib library, which Auth0's own Django quickstart uses. Authlib handles the redirect to Universal Login and the token exchange, and Django keeps the user in its session. We add role checks from token claims, a logout that clears both sessions, and tests for each protected view.

  • Auth0 SSO between applications works through one tenant and one session. When a customer signs in to your first app, Auth0 sets a session cookie on its domain. Your second app redirects to Auth0, finds that session, and gets tokens without a password prompt. Each app still checks its own tokens and roles.

  • An Auth0 SAML integration works in one of two directions. As a service provider, Auth0 accepts a business customer's SAML identity provider through an enterprise connection. As an identity provider, Auth0 signs users into a SAML-only app through its SAML2 Web App addon. We set up and test whichever direction your customers need.

  • Yes. Auth0's Self-Service Single Sign-On lets you send a customer's IT admin a setup link that expires after 5 days. They configure their SAML or OIDC connection in a guided assistant, and it attaches to their Organization in your tenant. Enterprise onboarding then stops waiting on your engineers.

  • Yes, when your current password hashes use a format Auth0 supports, such as bcrypt, argon2, or PBKDF2. Users move in a bulk import that keeps their hashes, or lazily at their next sign-in through a custom database connection. Unsupported formats need a reset, so we check yours during the free review.

  • Auth0 Rules and Hooks are deprecated, and Actions replace them. Tenants created since October 2023 can't use them, and Auth0 has announced their removal without a final date. We rewrite each Rule or Hook as an Action, test it against every app that reads its claims, then retire the old version.
