Google Chrome Third-Party Cookie Phase Out: What It Means for Your Online Services

What’s Happening with Third-Party Cookies?

Google Chrome is phasing out support for third-party cookies as part of its Privacy Sandbox initiative. This is a significant shift in how websites track user activity and deliver personalized experiences — and it has real implications for financial institutions and their digital services.

Key Terms to Know

  • Cookies: Small pieces of data stored in a web browser, commonly used to maintain user sessions, remember preferences, and track activity across websites.
  • Third-party cookies: Cookies set by a domain other than the one you’re currently visiting. For example, if your online banking portal embeds a third-party analytics or mapping service, that service’s cookies are considered third-party.
  • Inline frames (iFrames): A method websites use to embed content from other websites. If your banking site embeds a map or chat widget, that embedded content runs inside an iFrame.
  • Partitioned Cookies (CHIPS): A new standard called Cookies Having Independent Partitioned State that allows third-party services to function without cross-site tracking.

How This Affects Financial Institutions

Many banks and credit unions rely on third-party integrations within their online portals — analytics tools, customer support widgets, embedded applications, and more. When Chrome blocks third-party cookies, some of these integrations may stop working as expected.

Common areas of impact include:

  • Online banking portals that embed third-party services
  • Analytics and tracking tools used to measure customer engagement
  • Embedded widgets such as chat, maps, or calculators from external providers

What You Should Do

  1. Audit your digital properties: Identify where third-party cookies are used in your online banking, statement portals, and customer-facing websites.
  2. Work with your vendors: Confirm that your third-party service providers are updating their integrations to support partitioned cookies (CHIPS) or alternative approaches.
  3. Test in Chrome: Use Chrome’s developer tools to simulate cookie restrictions and verify your services still function correctly.
