Auth0 plans
| Plan | Price | What it covers |
|---|---|---|
| Free | $0 | Up to 25,000 MAU (B2C) / 500 MAU (B2B); includes social connections, basic MFA, and community support. |
| B2C Essentials | from $35-$70/mo (500 MAU) | Adds passwordless, MFA, role-based access; entry price for B2C scaled to MAU (raised toward $70/mo in late 2025). |
| B2B Essentials | from $150/mo (500 MAU) | Organizations support (unlimited orgs), B2B-oriented features, scaled by MAU. |
| B2C Professional | from $240/mo (1,000 MAU) | Adds external user databases, more MFA options (phone/email/WebAuthn/Guardian push), enhanced attack protection, longer log retention. |
| B2B Professional | from $800/mo (1,000 MAU) | Professional feature set for B2B with organizations and advanced protection, scaled by MAU. |
| Enterprise | Custom | Custom user/SSO tiers, 99.99% SLA, enterprise rate limits, advanced admin/support, private cloud options. |
- MAU-based pricing with hard caps gets expensive fast at scale; widely called a startup 'growth penalty'
- Post-Okta pricing changes seen as steep and unpredictable (reports of large bill jumps and a B2C Essentials hike)
- B2B-critical features (enterprise SSO connections, higher rate limits, custom SLA, private cloud) gated behind custom Enterprise pricing

- Per-connection SSO/Directory Sync pricing ($125/connection/mo) scales with customer count, not revenue, the most common complaint
- A single SSO customer can cost more than a SaaS vendor's own lowest-tier plan, blocking SSO-on-all-tiers strategies
- Audit log and SIEM streaming add-ons stack additional monthly costs
