Compare Auth0 vs. AuthStack

Auth0 takes a modern approach to Identity and enables organizations to provide secure access to any application, for any user. Auth0 is highly customizable, and simple yet flexible. Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. With Auth0, you can rapidly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control.

AuthStack is a robust, enterprise-level Single Sign-On (SSO) and Identity Access Management (IAM) solution that can be hosted anywhere. It efficiently manages user logins not only for your own websites and applications but also for third-party platforms, simplifying the process by allowing users to authenticate just once with a single password and profile. Instead of juggling numerous logins for different services, AuthStack streamlines user identity management into a singular experience. For those whose websites or applications support SAML, integrating with AuthStack is straightforward and requires no custom development. In cases where SAML support is absent, a complimentary Connector Framework is available, and assistance with integration can be provided if needed. Additionally, transitioning to AuthStack does not necessitate migrating your current user databases, as the Connector Framework can seamlessly interface with various data sources, including LDAP, MySQL, SOAP, and REST APIs, to verify credentials against existing user records. This means you can enhance security and user convenience without overhauling your existing systems.
