Overview
Auth0 is a cloud-based identity and access management (IAM) platform that provides authentication and authorization services for web, mobile, and legacy applications. Founded in 2013, the company built a developer-friendly platform that enables organizations to quickly implement secure login and identity management features without building authentication infrastructure from scratch. Auth0 supports multiple authentication methods including social logins, multi-factor authentication, single sign-on, and passwordless authentication. In May 2021, Auth0 was acquired by Okta for approximately $6.5 billion, representing one of the largest acquisitions in the identity management space. Following the acquisition, Auth0 continues to operate as a distinct product line within Okta's portfolio, maintaining its brand, developer-focused approach, and product roadmap while benefiting from Okta's enterprise resources and customer base. While Auth0 is not strictly an AdTech company, it plays a supporting role in the digital advertising ecosystem by providing identity management and authentication services that help AdTech platforms manage user identities, secure customer data, implement privacy controls, and ensure compliance with regulations like GDPR and CCPA. Its APIs and SDKs are used by various AdTech companies to handle user authentication and access control.
