Leading customer identity and access management platform, now part of Okta's Customer Identity Cloud
Overview
Auth0 is an identity and access management (IAM) platform that provides authentication and authorization services for applications and APIs. While not a traditional AdTech company, Auth0 plays a supporting role in the digital ecosystem by enabling secure user identity management, which is crucial for personalized advertising, user tracking, and consent management. The platform offers developers pre-built authentication solutions including social login, multi-factor authentication, single sign-on, and user management capabilities. Auth0 was acquired by Okta in 2021 for $6.5 billion, becoming part of Okta's Customer Identity Cloud. The platform serves over 13,000 customers globally and processes billions of logins monthly, making it one of the leading identity platforms for both B2C and B2B applications. In the context of AdTech, Auth0's identity solutions enable publishers and advertisers to manage user identities securely while maintaining compliance with privacy regulations like GDPR and CCPA.
