First ID is a powerful solution that enables you to identify and recognize your consented users across all your websites, devices, and browsers without being dependent on email or third-party cookies. With the increasing restrictions on third-party cookies (up to 90% of users becoming invisible), First ID provides a deterministic and persistent identification solution.

​
What is First ID?

First ID allows you to:
  • Identify and recognize all your consented users
  • Work across all domains, devices, and browsers
  • Operate without relying on email or third-party cookies
  • Maintain GDPR compliance with user consent management
  • Provide deterministic and persistent identification

​
Getting Started

To integrate First ID into your Edgee project:
  1. Open the Edgee console and navigate to your project’s Components.
  2. Select “Add a component” and choose first-id/first-id from the list of available components.
  3. Configure the component settings:
The component offers several configuration options:
  • Consent Mode: Controls when the First ID is set
    • safe: Only set ID after user grants consent (default)
    • strong: Set ID unless user explicitly denies consent
    • always: Set ID regardless of consent status
Using strong or always modes may not comply with privacy regulations in your jurisdiction (such as GDPR, CCPA, or other applicable laws). By enabling these modes, you assume full responsibility for:
  • Ensuring compliance with all applicable privacy laws and regulations
  • Obtaining and managing necessary user consents
  • Implementing appropriate privacy notices and policies
  • Any legal consequences resulting from non-compliant identification
Edgee provides these features as technical capabilities only. We strongly recommend consulting with your legal team or privacy experts before implementing these modes.
