We read that on 2026-10-07 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 - 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
