Overview
Auth0 launched in 2013 as a developer-first identity service and was acquired by Okta in 2021. It remains the reference CIAM platform for engineering teams that want extensibility through Actions, Rules, and a deep SDK catalog.
When to choose Auth0
Pick Auth0 when developer experience drives the decision and you need broad protocol coverage out of the box. The SDK and quickstart surface remains the strongest in the category.
When to look elsewhere
Watch the per-MAU economics above 1M users. Negotiation matters and list pricing is rarely what enterprises pay.
