Microsoft has announced that it will discontinue its method of collecting data related to user devices and browsers. Instead, the company will transition to the User-Agent Client Hints API, which is more privacy-focused and standardized.
Microsoft is phasing out the non-standard Microsoft Edge method, window.external.getHostEnvironmentValue(), which allowed web developers to access browser and platform information.
The goal is to enhance browser privacy by eliminating user fingerprinting. The UA Client Hints API provides browser and platform details in a more privacy-preserving manner, as the browser can decide what information to share when prompted. Low-entropy hints are accessible with every request, while high-entropy hints, which could reveal more fingerprinting details, can be restricted based on user preferences or require explicit permission.

The User-Agent Client Hints API is built on the Client Hints framework, enabling websites to access browser and platform specifics while minimizing the data footprint users leave behind during browsing. This approach ensures websites still receive sufficient information to deliver an optimal experience.
The phase-out will follow a detailed schedule, outlined in the table below.
Although the complete removal of the method is still some time away, this is positive news for privacy-conscious users, as it represents a step forward in safeguarding browser privacy compared to previous practices.
