They have been read-only since November 18, 2024, and tenants created from October 16, 2023 never had them. Auth0 says to move to Actions. Source ↗ (effective 2028-01-31)View in changelog →
The day we last read the vendor's page. Our last read of it, on 2026-11-01, found the page different from the terms we hold. We hold no confirmation of the terms we publish — the 2026-08-15 beside this date is not one we can source to a read that confirmed them.
Free Tier Details
Identity platform — 25K MAU (B2C), unlimited logins, social + database connections, Universal Login, 1 Enterprise Connection, 5 Organizations, 1 Custom Domain. No credit card required
We read that on 2026-11-01 from https://auth0.com/pricing, and our check recorded: the page names Auth0 as "auth0" and states "$ 0". A source check reads the cited page for the service's name and a price; the limits above are from our own record.
Using the Free plan's custom domain requires a valid credit card on file for verification and fraud prevention. Auth0 does not charge it. (From auth0.com/docs/customize/custom-domains, read 2026-10-08.)

Data correction - our Auth0 Rules and Hooks record carried the November 18, 2026 date that Auth0's docs gave when we read them on 2026-10-12. Read on 2026-10-31, Auth0's docs date Hooks April 30, 2027 and Rules January 31, 2028, so that record now covers Hooks and a second record covers Rules. Source ↗
Before: One record for Rules and Hooks, dated 2026-11-18
After: Hooks dated 2027-04-30 and Rules dated 2028-01-31, from Auth0's docs
Data correction - Auth0 raised its Free plan from 7,500 to 25,000 monthly active users on 2024-09-24, not 2025-11-01: Auth0's post "Auth0 plans got an upgrade" is dated 2024-09-24 and says the updates were "available as of September 24th, 2024". The record's after state also listed MFA on the Free plan; the post's MFA increases are for the paid plans. Source ↗
Before: Dated 2025-11-01 (hand-written); after state included MFA
After: Dated 2024-09-24 from Auth0's announcement; after state from the announcement's Free plan list
Auth0's Free plan went from 7,500 to 25,000 monthly active users, with unlimited social and Okta connections, Organizations, Passwordless authentication and a custom domain. Auth0 announced it on 2024-09-24, available that day. Source ↗
