Auth0 is a leading customer identity and access management (CIAM) platform, now owned by Okta following a $6.5 billion acquisition in 2021. Used by over 18,000 customers including Mozilla, Sharp, and Mazda, Auth0 provides developers with a flexible, drop-in authentication solution supporting social login, passwordless authentication, multi-factor authentication, and enterprise connections via SAML and OIDC.

Auth0 pricing is based on Monthly Active Users (MAUs) rather than per-seat licensing. The free plan supports up to 25,000 MAUs with basic features. Paid plans start at $35/month for B2C Essentials (500 MAUs) and $150/month for B2B Essentials (500 MAUs). Professional plans begin at $240/month (B2C) and $800/month (B2B) for 1,000 MAUs. Enterprise pricing is custom. A key consideration is that costs can escalate rapidly as your user base scales, with MAU overage charges of $0.07 per user.

Hidden Costs to Budget For

Watch for 8 hidden costs
  • MAU overage charges: Exceeding your plan's MAU limit costs $0.07/MAU — a 300% increase from the previous $0.023/MAU rate
  • Pricing cliffs: Companies report cost jumps from $3,000/year to six-figure contracts after crossing 10,000 B2B MAUs or 30,000 B2C MAUs
  • B2B premium: B2B plans cost 3-4x more than B2C equivalents (e.g., B2B Professional is $800/mo vs B2C Professional at $240/mo)
  • Enterprise MFA add-on: Advanced MFA with push notifications, WebAuthn, and hardware keys requires an additional paid add-on on non-Enterprise plans
  • Bot detection add-on: Enhanced bot detection and brute-force protection is a paid add-on not included in base plan pricing
  • Migration complexity: Moving away from Auth0 requires significant engineering effort to rebuild authentication flows, making vendor lock-in a hidden long-term cost
  • Custom domain costs: Custom domains are not available on the Free plan, requiring at minimum an Essentials subscription
  • Private Cloud deployment: The private deployment option on Enterprise plans adds substantial cost beyond the base subscription
Tip

Ask your Auth0 sales rep about these costs upfront. Getting them in writing before signing can save you from surprise charges later.

Frequently Asked Questions

01 How much does Auth0 cost?

Auth0 has a free tier for up to 25,000 MAUs. Paid plans start at $35/month (B2C Essentials) for 500 MAUs. Professional plans start at $240/month (B2C) or $800/month (B2B) for 1,000 MAUs. Enterprise plans require custom pricing. Costs scale significantly as your user base grows.

02 Does Auth0 have a free plan?

Yes, Auth0 offers a free plan that supports up to 25,000 Monthly Active Users. It includes password and social login, branded login forms, and basic security. However, it lacks custom domains, MFA, enhanced security, and production-grade support, making it best suited for development and early-stage projects.

03 How does Auth0 pricing scale with users?

Auth0 uses MAU-based pricing that scales in tiers. Essentials starts at $35/month for 500 MAUs, and costs increase as you add more users. Overages are charged at $0.07/MAU. Many companies report dramatic cost increases as they grow — one company saw their bill jump 15x when their user base grew just 1.67x due to tier jumps.

04 What is the difference between Auth0 B2C and B2B plans?

B2B plans cost significantly more (3-4x) than B2C plans because they include enterprise connections (SAML, OIDC), multi-tenant organization management, and organization-level branding. B2C Essentials is $35/month while B2B Essentials is $150/month, both starting at 500 MAUs.

05 Is Auth0 expensive compared to alternatives?

Auth0 is considered premium-priced in the identity space. While its free tier is generous at 25,000 MAUs, paid plans escalate quickly. Alternatives like Firebase Auth (free up to 50K MAUs), Clerk, and SuperTokens offer more affordable scaling. Auth0's strength is its developer experience and comprehensive feature set.

06 Can I negotiate Auth0 pricing?

Yes, especially at the Enterprise tier. Auth0 (owned by Okta) offers negotiated pricing for high-volume customers. Request quotes from competitors like Firebase, AWS Cognito, or Clerk for leverage. Multi-year contracts and annual prepayment can yield 10-25% savings.
