The Privacy Sandbox team was at Google I/O 2024 to share the latest news on third-party cookie deprecation, and help developers transition to alternatives.
Google I/O is Google's annual developer conference. For the first time since 2019, Google I/O this year was an in-person, two-day event.
Privacy Sandbox hosted a live session to help developers prepare their sites to transition away from third-party cookies. We gave an overview of Privacy Sandbox across web and Android, and we demonstrated the PSAT tool to hundreds of developers.
Here are the highlights.
A more private ecosystem on Chrome and Android
Understand how Privacy Sandbox works across Chrome and Android:
- Understand product roadmaps
- Explore new APIs and features
- Learn about privacy-preserving APIs
What you need to know about third-party cookie deprecation
Chrome plans restrict third-party cookies by default, with rollout beginning in early 2025.
Prepare for third-party cookie restrictions:
- Understand the phaseout timeline
- Audit cookie usage
- Test for breakage
- Transition to alternatives
Use passkeys and FedCM for better authentication experiences
A passkey is a digital credential that allows users to authenticate without having to enter a username or password, or provide any additional authentication factor.
The Federated Credential Management API (FedCM) provides a standardized mechanism for identity providers to make their services available without the need for third-party cookies and redirects.
This session will help you learn how to use passkeys and FedCM to enable more secure and user-friendly authentication experiences:
- Audit your sites
- Prepare for upcoming third-party cookie restrictions.
- Explore new API features and learn about new capabilities that enhance trust on the web
Privacy Sandbox Analysis Tool (PSAT)
PSAT is a Chrome extension that enhances Chrome DevTools with multiple features to help you transition away from third-party cookies.
You can download PSAT from the Chrome Web Store: goo.gle/psat.
