💡 Pro tip: Most tools offer free trials or free tiers. Test 2-3 options side-by-side to see which fits your workflow best.
Auth0 charges based on Monthly Active Users (MAUs) - users who log in at least once per month. The Essential plan starts at $23/month for 1,000 MAUs, then $0.05 per additional MAU. B2C features like social logins are included, but B2B features like SAML connections cost extra. If you have 50,000 registered users but only 10,000 log in monthly, you pay for 10,000 MAUs, not 50,000 total users.
Yes, through Custom Database Connections, you can keep user data in your existing database while using Auth0 for authentication. Auth0 provides scripts to authenticate users, create accounts, verify emails, and reset passwords against your database. You can migrate users gradually - Auth0 authenticates against your database first, then imports users to Auth0's database upon successful login, eventually deprecating the legacy database.
Rules are the legacy system using Node.js 8 with limited npm modules, while Actions are the modern replacement using Node.js 18+ with full npm support and better debugging tools. Actions provide versioning, better error handling, and integration with Auth0's dashboard for testing. New implementations should use Actions, and Auth0 provides migration tools to convert existing Rules to Actions with minimal code changes.
Auth0 provides built-in GDPR compliance tools including user data export APIs, right-to-be-forgotten deletion workflows, and data processing agreements.
