When Auth0 is not a good fit
Auth0 is an identity and access management platform, owned by Okta since 2021, that adds login, authentication and authorization to applications through prebuilt SDKs and APIs. It supports social login, single sign-on, multi-factor authentication and role-based access control for both consumer (B2C) and business (B2B) applications. As of September 2026 its free plan covers up to 25,000 monthly active users.
It is a weaker choice for:
- Very high monthly active user counts on a budget, since paid plans price by MAU and can get expensive
- Teams that want a self-hosted, open source identity system
- Simple apps that only need basic email and password login without enterprise features
