What is Auth0?
Auth0 is the developer-friendly customer identity platform now owned by Okta. It handles login, signup, social auth (Google, Apple, Facebook, etc.), enterprise federation (SAML, OIDC), MFA, anomaly detection, and progressive profiling for apps. Universal Login is a hosted, customizable auth flow that handles all the security minutiae developers shouldn't write themselves. Auth0 Actions let developers run custom code in the auth pipeline (Node.js). Adaptive MFA, Bot Detection, and Breached Password Detection raise the security bar without UX cost. Pricing has long been generous on a free tier (7,500 active users), though recent changes pushed power features to higher tiers. It's the default identity stack for SaaS startups.
Auth0 offers a freemium pricing model starting at $23/month. A free tier is available with limited features. Platform availability information is not currently listed.
