Auth0 Coupon: 1 year of B2B Professional free

Deal Highlights

Auth0 is an identity platform that handles login, signup, multi-factor authentication, single sign-on and user management for web, mobile and API products. Okta acquired Auth0 in May 2021 in a stock deal valued at about $6.5 billion, and Auth0 now runs as Okta's developer-focused customer identity product. You add Auth0 to your app with an SDK, point users at a hosted login page, and get back standard OpenID Connect and OAuth 2.0 tokens. Your team does not store passwords, build MFA flows or write SAML integrations by hand.

The startup program matters most if you sell to businesses. B2B buyers ask for enterprise SSO, SCIM provisioning and MFA early, often in the first security questionnaire. On Auth0's public pricing, the plan that bundles those features, B2B Professional, starts at $800 per month for 500 monthly active users. Auth0 for Startups gives eligible companies that plan free for 12 months, with up to 100,000 monthly active users. For a seed-stage team closing its first enterprise contracts, that removes a four-figure monthly bill during the year when cash is tightest. Independent deal listings put the value at roughly $24,000. That figure is a third-party estimate, not an official Auth0 number.

What Is Auth0?

Auth0 is a hosted authentication and authorization service. It sits between your application and your users. When a user signs in, Auth0 verifies who they are, applies your rules, and issues tokens your app and APIs can trust.

The platform covers the standard identity work most products need:

• Username and password login with breached password detection and brute force protection.
• Social login with Google, Microsoft, GitHub, Apple and many other providers.
• Passwordless login with email magic links or one-time codes.
• Multi-factor authentication with authenticator apps, SMS, WebAuthn and push.
• Enterprise connections to a customer's identity provider over SAML, OIDC, Microsoft Entra ID, Google Workspace and similar protocols.
• Machine-to-machine tokens for service accounts and backend APIs.

Auth0 splits its paid plans into two tracks. B2C plans target consumer apps. B2B plans target SaaS products whose customers are companies, and they add Organizations, more enterprise connections and SCIM. The startup program is built on the B2B track.

Auth0 is standards-based. Tokens are JWTs. Login uses OIDC and OAuth 2.0. Enterprise SSO uses SAML or OIDC. That matters for lock-in. Your backend validates standard tokens, so your API code does not depend on Auth0-specific libraries. Migrating away later still takes work, mostly around user data export and login flows, but your authorization logic stays portable.

What the Startup Program Includes

The offer, as listed on auth0.com/startups, is one year of the B2B Professional plan at no cost. It includes:

• Up to 100,000 monthly active users. On the public price list, B2B Professional starts at $800 per month for 500 MAU, and cost rises as MAU grows.
• Enterprise MFA. Stronger second factors than the Free plan offers, which helps when a customer's security team reviews your login flow.
• Unlimited Organizations, subject to system limitations. Organizations is Auth0's model for multi-tenant B2B apps. Each customer company becomes an Organization with its own members, roles, branding and login options.
• 3 Third-Party APIs, including Token Vault. Token Vault stores and refreshes OAuth tokens for external services such as Slack or GitHub, so your app or AI agent can call those APIs on a user's behalf.
• Inbound SCIM. Your customers can provision and deprovision their employees in your app from their own directory.
• 5 Enterprise Connections. Five customer identity providers connected over SAML, OIDC or similar protocols. Each enterprise customer that wants SSO typically uses one connection.

The deal runs for 12 months. There is no promo code and no partner code. You apply directly on Auth0's site. SaaSOffers lists the deal and links to the official page, but you do not need a SaaSOffers account, referral or code to get it.

A note on older information: an Auth0 blog post from August 5, 2020 is titled "Auth0 Startup Plan Now Free for Everyone." Despite the headline, it described a program limited to eligible startups, and it used a $2M funding cap. Auth0 raised that cap to $5M in November 2022. Treat the current startups page as the source of truth, not the 2020 post.

Who Qualifies

Your company must meet all three criteria:

1. Venture-backed with less than $5M in funding. Bootstrapped companies do not meet the stated criteria.
2. Less than $1M in annual recurring revenue.
3. Less than two years from the date of incorporation.

You also need a live website and a professional email address on your company domain. A Gmail address and a placeholder landing page make approval unlikely.

The offer is not available to:

• Existing paid Auth0 or Okta customers, on either enterprise or self-service plans.
• Startups that were already enrolled in the Auth0 for Startups program.

If you already pay for Auth0, this deal is not for you. If you are on the Free plan, you are not a paid customer, but check the terms on the application form before you apply.

Key Features

Universal Login. Auth0 hosts the login page on its own domain or on your custom domain. You redirect users there and get tokens back. Security fixes and new login methods ship without changes to your app. You can brand the page and customize its text.

Social and enterprise connections. Social login providers are unlimited on every plan, including Free. Enterprise connections let a customer's employees sign in with their company identity provider. The startup plan includes 5.

Multi-factor authentication. Auth0 supports one-time passwords, WebAuthn security keys and device biometrics, push notifications through Auth0 Guardian, SMS and email. The startup plan includes Enterprise MFA.

Passwordless. Users sign in with a magic link or a one-time code sent by email or SMS. Auth0 made passwordless available on the Free plan in September 2024.

Organizations. Each customer account in your B2B app maps to an Organization. You can invite members, assign roles per Organization, show a login page branded for that customer, and require a specific enterprise connection for a given customer. This is the core feature for multi-tenant SaaS.

Actions. Actions are Node.js functions that run at points in the auth pipeline, such as after login or before user registration. Common uses: add custom claims to tokens, block sign-ups from certain domains, sync new users to your CRM, or call your own API to check account status. The number of Actions you can deploy depends on the plan.

Inbound SCIM. A customer's IT team can create, update and remove users in your app from Okta, Microsoft Entra ID or another directory. Offboarding happens automatically, which enterprise security reviews often check.

Auth0 Fine Grained Authorization (FGA). FGA is a relationship-based authorization service built on the open source OpenFGA project. It answers questions like "can this user edit this document" based on relationships, not only roles. It is a separate product with its own pricing, so check whether you need it before you design around it.

Auth0 for AI Agents and Token Vault. Auth0 announced general availability of Auth0 for AI Agents on November 19, 2025. It covers four pieces: user authentication for agents, Token Vault for third-party API tokens, asynchronous authorization for human approval before sensitive actions, and FGA for RAG to filter retrieved documents by user permissions. If you build agents that act in a user's Gmail, Slack or GitHub, Token Vault handles the OAuth token storage and refresh. The startup plan includes 3 third-party APIs with Token Vault.

Attack protection. Auth0 includes bot detection, brute force protection, suspicious IP throttling and breached password detection. Paid plans add enhanced options.

SDKs and quickstarts. Auth0 maintains SDKs for Next.js, React, Angular, Vue, iOS, Android, Flutter, Node.js, Python, Go, Java, .NET and more. Each has a quickstart guide in the Auth0 docs.

Pricing

These are Auth0's public list prices from auth0.com/pricing as of September 2026. Prices are monthly and scale with MAU. Annual billing is priced at 11 times the monthly rate.

Free plan. Up to 25,000 MAU, unlimited social connections, passwordless, 1 custom domain, 5 Organizations, basic attack protection, 1 enterprise connection, self-service SSO and SCIM. Auth0 raised the Free plan from 7,500 to 25,000 MAU on September 24, 2024. Older reviews that quote 7,500 MAU are out of date.

B2B Essentials. Starts at $150 per month. Adds unlimited Organizations and 3 enterprise SSO connections.

B2B Professional. Starts at $800 per month. Adds 5 enterprise connections, Enterprise MFA, enhanced attack protection, custom database connections and more Actions. This is the plan the startup program gives you for free.

Enterprise. Custom pricing, a 99.99% SLA and enterprise support.

What happens after the free year. The program covers 12 months. After that, you pay list price for the plan and MAU volume you need, move to a cheaper plan, or drop to the Free plan if your usage fits its limits. The Free plan's 25,000 MAU is generous, but it caps you at 5 Organizations and 1 enterprise connection. A B2B app with 10 enterprise customers on SSO will not fit on Free. Model your month 13 bill before you design around Professional features. Confirm the exact renewal terms with Auth0 during onboarding.

How to Claim the Deal

1. Open https://auth0.com/startups.
2. Click the apply button and fill out the form. Use your business email on your company domain and give the URL of your live website. Have your funding amount, incorporation date and ARR ready.
3. Wait for approval. Approval reportedly takes 1 to 2 business days. Auth0 does not publish a fixed timeline.
4. Once approved, the B2B Professional plan is applied to your Auth0 tenant for 12 months. Create the tenant first if you do not have one, and note which tenant you want upgraded.

You do not need a SaaSOffers account, a referral or a code. The application goes straight to Auth0.

Who It's Best For

B2B SaaS startups selling to mid-market and enterprise. If your roadmap has SSO, SCIM and per-customer login policies in it, this plan covers all three from day one. You can say yes to the first customer who asks for SAML.

Teams that want to skip building auth. A small team can spend weeks on login, password reset, MFA enrollment and session handling. Auth0 hands that work to a vendor with a security team.

AI agent products. If your product calls third-party APIs on behalf of users, Token Vault and the AI agent features solve token storage and refresh, which is tedious to build safely.

Founders who expect a security review. Auth0 publishes compliance documentation, and "we use Auth0" is a familiar answer on vendor questionnaires.

It is a weaker fit for consumer apps with millions of free users, where MAU pricing grows fast, and for teams that need full control of the identity stack on their own infrastructure.

Pros and Cons

Pros

• 12 months of the $800+ per month B2B Professional plan at no cost, with up to 100,000 MAU.
• Enterprise SSO, SCIM and Organizations are ready when your first enterprise customer asks.
• Standards-based. OIDC, OAuth 2.0 and SAML keep your API code portable.
• Wide SDK coverage across web, mobile and backend languages.
• Actions let you customize the login pipeline in JavaScript.
• Mature product backed by Okta, with a large base of docs and community answers.
• The Free plan at 25,000 MAU is a real fallback for smaller products.

Cons

• Pricing steps up sharply between tiers and as MAU grows. Reviewers on G2 and elsewhere name cost at scale as the top complaint.
• Useful B2B features sit on the more expensive plans. After the free year, keeping Professional features means paying Professional prices.
• The dashboard and configuration model take time to learn. Tenants, applications, APIs, connections, Organizations and Actions all interact.
• Deep customization of Universal Login is more limited than a login UI you own.
• Strict eligibility. Bootstrapped companies, companies older than two years and anyone who has paid for Auth0 before are excluded.

Alternatives

Clerk. Drop-in UI components and a fast setup for React and Next.js apps. Easier to start than Auth0, with less depth in enterprise federation.

WorkOS. Built for B2B SaaS that needs enterprise SSO and directory sync. Pricing is per connection, which can be cheaper than Auth0 if you have few enterprise customers and many users.

Stytch. API-first auth with strong passwordless and B2B features. A good fit for teams that want to build their own UI on top of flexible primitives.

Supabase Auth. Bundled with the Supabase Postgres platform and tied into its row level security. The simplest choice if you already run on Supabase, with fewer enterprise identity features.

Firebase Authentication. Google's auth service, cheap and easy for consumer and mobile apps. Enterprise SSO and multi-tenant B2B require the Identity Platform upgrade.

AWS Cognito. Low per-user cost and native AWS integration. The developer experience and hosted UI are widely considered harder to work with than Auth0.

Keycloak. Open source and self-hosted, with full protocol support and no per-user fees. You run, patch and scale it yourself.

Tips to Get the Most Out of Auth0

1. Use separate tenants for development, staging and production. Keep test users, test connections and experimental Actions out of production. Confirm which tenant should get the startup plan when you apply.
2. Plan for month 13 on day one. Write down your expected MAU and the number of enterprise connections you will need at the 12 month mark. Price that against the public plans. If you will outgrow the Free plan, budget for it or design so you can drop Professional-only features.
3. Model every customer as an Organization from the start. Retrofitting multi-tenancy is painful. Put each customer company in its own Organization so per-customer SSO, roles and branding work without a migration later.
4. Keep Actions small and versioned. Store Action code in your repository and deploy it through the Auth0 Deploy CLI or Terraform provider. Avoid long network calls in the login path, since every second there is a second your user waits.
5. Validate tokens in your own code with standard libraries. Check the issuer, audience and signature using your language's JWT library. That keeps your APIs portable if you change identity providers later.
