Offers
Auth0 Free Plan (always-free tier) high confidence
$0/month, permanent. Up to 25,000 MAU; 1 tenant; 1 custom domain; 1 Enterprise Connection (added Feb 2026); Self-Service SSO and Inbound SCIM (added Feb 2026); unlimited Social Connections; unlimited Okta Connections (subject to system limitations); 5 Organizations on B2C, Unlimited* Organizations on B2B; 3 Admin/Contributor seats; 5 Actions + Forms; 1 Event Stream; 1,000 M2M tokens; 1-day log retention; 2 Token Vault slots; passwordless auth, passkeys, brand customization, Basic Attack Protection (brute force + suspicious IP throttling), community support, Inbound SCIM, Okta Universal Logout integration. No credit card needed to sign up. Sign up at https://auth0.com/signup (or dev.auth0.com/signup); the Free plan is the default subscription. Email Workflow is NOT available on Free. Exceeding 25,000 MAU triggers a quota warning; you cannot self-upgrade past the free cap without contacting sales.
Eligibility
Anyone globally — no .edu email, no startup proof, no funding or age cap. No credit card required for the free plan itself. Free tenants historically available in 5 regions (US, UK, EU, JP, AUS).
How to claim
Sign up free at auth0.com/signup; the Free plan is automatic — no application, no card. Custom domain: add it in dashboard (a card is collected purely for verification and, per Auth0's FAQ, you are never charged).
Expiry
No expiry — free forever, as of 2026-10-22. Existing free tenants had entitlements auto-applied when the plan was upgraded (Sep 2024).
Gotchas
1 tenant max on Free (one 'team' per team-owner email; a second team needs a different email). Credit-card verification required to add the 1 custom domain (verification only, never billed, per official FAQ). 1-day log retention, no email workflows, no log streaming, no Pro MFA, no Role Management/Account Linking, no CIBA — many 'everything in Free, plus' claims in the marketing copy don't change these exclusions. 25,000 is an MAU cap (users who authenticated in a calendar month), not a total-user cap. Unlimited* is 'subject to system limitations'.
22-day paid-features trial (auto-activated on new tenants) medium confidence
New tenants automatically get a 'Starter Trial' subscription giving up to 22 days of paid-plan features (e.g., Pro MFA, higher API/feature limits) at $0, no credit card. When the 22 days elapse, the tenant automatically moves to the Free plan with no charge. Confirmed by Auth0 support/community staff (2023–2025) and by the Sept 2025 support article 'What Happens when the Auth0 Free Trial Expires'.
Eligibility
Any new tenant/creator; up to 3 tenants per free account before the trial/teams limits matter. No card, no .edu, no startup criteria.
How to claim
Just create a tenant; the trial activates automatically. Do NOT create a tenant just for the trial if you want to stay clean — the trial lapses on its own into Free.
Expiry
22 days per tenant from creation, then automatic drop to Free plan; tenant older than 22 days cannot re-trial paid features (per community guidance).
Gotchas
Trial-of-paid is distinct from the Free plan; paid features are locked after day 22 unless you subscribe. The pricing page itself does not advertise the 22-day trial, so treat exact day count as community-confirmed (21–22 days reported in different threads). No CC required for the trial itself (CC only if you later add a custom domain or subscribe).
12 months of the B2B Professional plan free: up to 100,000 MAU, Enterprise MFA, unlimited* Organizations, 5 Enterprise Connections, 3 Third-Party APIs via Token Vault, Inbound SCIM. Trusted by 4,000+ startups. A partner channel exists (e.g., Mercury Perks) offering the same 12-month free B2B plan under looser-looking criteria (less than $5M raised and less than $1M ARR), for that bank's customers. After the 12 months, the company moves to self-service paid plans or Enterprise.
Eligibility
Venture-backed, less than $5M total funding, less than $1M annual recurring revenue, less than 2 years from incorporation. NOT valid for existing paid Auth0/Okta customers (enterprise or paid self-service) or companies that were previously in the program. No .edu path; no region limit stated on the official page (global program).
How to claim
Apply at https://auth0.com/startups ('Apply now' routes to a Jira Service Desk portal, autheco.atlassian.net). Review takes days-to-weeks per third-party listings. Recommended path per Auth0: start on the Free plan during build, apply at launch. No card required for the free year.
Expiry
Fixed 12-month term per program; no second participation (prior members excluded); after expiry you migrate to standard paid pricing (B2B Essentials from $150/mo at 500 MAUs).
Gotchas
Must be VENTURE-backed — bootstrapped or solo startups under 2 years do not qualify (even though the 2020 version of the program was opened to 'anyone' meeting criteria). 100k MAU and 5 Enterprise Connections are hard caps for the free year. The program covers B2B Professional capabilities, not Enterprise plan tiers.
Education / student offer: none (no .edu license or student discount) medium confidence
Auth0 has no student plan, education license, or .edu-based discount. An Auth0 community manager confirmed in Dec 2024 that 'there aren't any special subscription plans for students; the best plan you could use would be the free plan.' The only education-adjacent free offering is Auth0 Learning (learning.auth0.com), relaunched Aug 2026 after splitting from Okta Learning (Feb 2025): free on-demand courses and skill badges, no sign-in required for content — free education content, not a product license. The Auth0 Ambassador Program is a volunteer/evangelism program (swag, travel for talks), not a free product tier, and is open to any developer, not students specifically.
Eligibility
N/A for a license — the Free plan's eligibility (anyone, no .edu) is what students actually use.
How to claim
N/A — nothing to claim. Students should use the Free plan at auth0.com/signup and the free Auth0 Learning content.
Expiry
N/A
Gotchas
Do not count on an .edu email unlocking anything at Auth0; any '.edu discount' claims circulating are unverified community anecdotes.
