Auth0 deal: Verified founder pricing
Auth0 review: the developer-friendly identity platform that quietly powers logins for thousands of SaaS and B2C apps.

- Comprehensive protocol support: OAuth2, OIDC, SAML, WS-Federation
- Extensive social login providers and enterprise identity connections
- SDKs for virtually every language and framework
How Auth0 scored 71/100
6 weighted criteria, each scored out of 10 and published with its reasoning. Featured placements never move a score.
Deal Strength
5.0 /10The real value here is the free tier, not a coupon: Auth0 is free for up to 25,000 monthly active users, and startup-program and annual discounts are negotiated directly with sales. There is no exclusive promo code, so the offer is the generous free plan plus whatever founder pricing you can secure.
Value for Money
7.0 /10Auth0 pays for itself when it replaces months of building secure login, MFA and SSO in-house. Paid B2C plans start at $35/month and B2B at $150/month, but MAU-based pricing and $0.07 per-user overages mean bills scale fast at consumer volume, so the value is strongest for lower-volume, higher-stakes apps.
Capability
9.0 /10Auth0 is a leading customer identity platform (CIAM) with genuine depth: Universal Login, social and enterprise connections, passwordless and FIDO2 passkeys, MFA, B2B organizations for multi-tenant SaaS, and Actions for scripting custom login logic. SDKs cover React, Next.js, mobile and most major backend frameworks.
Time to Value
8.0 /10A basic login flow is live in an afternoon thanks to drop-in Universal Login and clean quickstart SDKs. The free tier lets teams ship without a contract, though wiring up enterprise SSO, custom Actions and complex multi-tenant rules adds real configuration time later.
Trust & Reliability
8.0 /10Auth0 is trusted at scale, blocking billions of malicious login attempts monthly and backing Enterprise plans with a 99.99% uptime SLA. Now Okta's Customer Identity Cloud since the 2021 acquisition, it inherits enterprise-grade compliance and infrastructure while keeping its own dashboard and developer experience.
Flexibility & Exit
6.0 /10Billing is flexible month to month with a free plan and no long lock-in on lower tiers, and users and profiles can be exported via the Management API. The catch is practical, not contractual: deep use of Actions, rules and org configuration creates real switching effort, and the sharpest features sit behind Enterprise pricing.

Free up to 25k MAUs. Annual contracts and startup-program discounts are negotiated directly with sales.

About Auth0
Quick answer
Auth0 is a customer identity and access management (CIAM) platform owned by Okta. It's best for engineering teams that want drop-in login, SSO, MFA, passwordless, and B2B org/tenant management delivered through clean SDKs and a mature rules engine — without standing up their own auth stack.
What is Auth0?
Auth0 is a customer identity platform founded in 2013 by Eugenio Pace and Matias Woloski and headquartered in Bellevue, Washington. In May 2021, Auth0 was acquired by Okta in a deal valued at roughly $6.5 billion, one of the largest identity-industry transactions on record. Post-acquisition, Auth0 continues to operate as a distinct product line within the Okta portfolio, focused primarily on customer-facing identity (B2C, B2B, and B2E), while Okta Workforce Identity covers employees.
At its core, Auth0 handles the boring-but-critical part of every modern application: who is this user, are they really who they say they are, and what are they allowed to do? It does this through a hosted login experience, a directory of users, dozens of social and enterprise identity providers, and a programmable runtime for custom auth logic.
Key features that actually matter in 2026
Universal Login
A hosted, customizable login page (no in-app credential handling required). Reduces your PCI/scope surface and ships with MFA, passwordless, and passkey support out of the box.
50+ Connections
Pre-built integrations for Google, Apple, Facebook, Microsoft, GitHub, plus enterprise SSO via SAML, OIDC, and LDAP/Active Directory. New social IdPs can be added via OIDC.
Actions & Triggers
Serverless functions (Node.js or Python via the OIDC runtime) that fire on login, registration, token exchange, and more — replacing the older Rules/Hooks system with a more transparent, version-controlled model.
B2B CIAM (Organizations)
Multi-tenant orgs with member invitations, roles, and connection isolation per tenant — purpose-built for SaaS products selling to other businesses.
SDKs Everywhere
First-class SDKs for React, Next.js, Vue, Angular, iOS, Android, Flutter, .NET, Java, Node, Python, Ruby, Go — plus quickstarts for almost every framework you'll encounter.
Enterprise Federation & SCIM
Federate to any IdP for SSO, and use SCIM to provision/de-provision users automatically. Critical for closing B2B deals where the buyer's IT team requires SAML and automated user lifecycle.
Auth0 pricing in 2026
Auth0 still publishes a generous free tier and a per-MAU pricing model on top of it. Exact public list prices shift, so confirm on the official pricing page before quoting, but the structure is well-known:
- Free: Up to roughly 7,000 monthly active users with email + password, basic social logins, and up to 2 connections. Enough for many MVPs, side projects, and small SaaS apps.
- Essentials (B2C): Custom domains, MFA, basic passwordless — historically from the ~$35/month range plus usage.
- Professional (B2C): Adds Actions, enterprise connections, log streaming, and 24/7 support — historically from ~$240/month plus usage.
- Enterprise (B2C): SLAs, private cloud/PSE, advanced security, and custom contract terms.
- B2B Essentials & Professional: Organizations, org-level connections, invitations — historically from ~$150/month for Essentials.
Where teams get burned is the active user model: as your product grows, MAU-based pricing scales with success. Plan for that, and Auth0 is excellent value; ignore it, and a $0 bill becomes a five-figure one fast.
Auth0 vs the alternatives
| Platform | Best for | Strengths | Watch-outs |
|---|---|---|---|
| Auth0 | Product teams that need flexible, developer-first CIAM | Mature SDKs, Actions, huge connection library, B2B org support | MAU pricing climbs at scale; some features locked to enterprise tier |
| Okta Workforce + CIC | Enterprises already standardized on Okta for employees | Unified workforce + customer identity; deep enterprise governance | Heavier admin experience; pricier for pure CIAM |
| AWS Cognito | AWS-native teams on tight budgets | Low entry price; tight IAM integration | Steeper learning curve; customization requires more Lambda glue |
| Firebase Authentication | Mobile-first apps in the Google ecosystem | Free generous tier; trivial setup for mobile | Less control over UI/branding; weaker B2B SSO story |
Who should (and shouldn't) buy Auth0
✓ Use Auth0 if you:
- Run a B2B SaaS selling to mid-market or enterprise buyers who require SAML SSO, SCIM, and org management.
- Want to ship login, signup, MFA, and passwordless in days, not quarters.
- Care about extensibility — Actions let you inject custom auth logic without forking the platform.
- Need to federate with dozens of social and enterprise IdPs out of the box.
- Want passkey/WebAuthn support without implementing it yourself.
✗ Skip Auth0 if you:
- Already pay for an Okta Workforce bundle and want to consolidate to Okta CIC.
- Need a fully on-prem or air-gapped deployment (Auth0 is SaaS, with Private Cloud as a premium add-on).
- Have a tiny user base and prefer a vendor without usage-based pricing.
- Want a turnkey CRM (Auth0 doesn't do pipeline, deals, or campaigns — it's identity infrastructure).

- Universal Login with social, enterprise and passwordless options

The bottom line
Auth0 is one of the most capable customer identity platforms a developer can drop into an app, with Universal Login, passwordless, MFA and enterprise SSO out of the box. Costs climb sharply past the free tier and there is no exclusive coupon, but for teams that need real authentication depth it is a clear Buy.
Auth0 is free for up to 25,000 monthly active users, then paid plans begin at $35/month for B2C Essentials and $150/month for B2B Essentials, both starting at 500 MAUs. Professional tiers run $240/month (B2C) and $800/month (B2B), with custom Enterprise pricing above that. Overage MAUs are billed around $0.07 each.
Auth0 has been part of Okta since the 2021 acquisition and now operates as Okta's Customer Identity Cloud. The Auth0 brand, dashboard, SDKs and developer experience continue unchanged, while compliance, security operations and infrastructure are shared with Okta on the back end.
The free plan covers up to 25,000 monthly active users with Universal Login, unlimited social connections, passwordless authentication and basic email/password login. Advanced capabilities such as enterprise SSO connections, role-based access control and enhanced attack protection require a paid B2C or B2B tier, so the free tier suits early builds more than production enterprise use.
Clerk is faster to integrate for a modern React or Next.js app and ships polished pre-built UI components, making it ideal for B2C startups. Auth0 wins when you need enterprise SSO (SAML, OIDC), complex multi-tenant organizations or strict compliance frameworks. Choose Clerk for speed and simplicity, Auth0 for enterprise identity depth.
Yes. Auth0 supports magic links, SMS and email one-time codes, biometric WebAuthn and FIDO2 passkeys, and these can be combined with traditional passwords in a single login flow. Multi-factor authentication is available on paid tiers, letting you layer passkeys or authenticator apps on top of any primary login method.
Auth0 is a strong fit if your near-term roadmap includes enterprise SSO, multi-tenant organizations or compliance requirements, and the 25,000-MAU free tier lets you start at no cost. If you are building a straightforward B2C app with no SAML in sight, lighter identity tools like Clerk or Supabase Auth are often cheaper and quicker to ship.
