Editorial Verdict
AI-researched, not hands-on testedAuth0's scale is real -- blocking 3 billion+ attacks monthly while scaling to 23 billion+ authentications, with genuine 99.99% uptime. The honest catch: MAU-based pricing can rise sharply and unpredictably as your user base grows, with some renewal quotes reported doubling or tripling, and support quality is reported as declining since the Okta acquisition.
