こんにちは TAG-さん!

The Federated Identity on the Web WG is requesting a TAG review of the Digital Credentials API.

This document specifies an API to enable user agents to mediate presentation and issuance of digital credentials such as a driver's license, government-issued identification card, and/or other types of digital credential . The API builds on Credential Management Level 1 as a means by which to request or issue a digital credential from a user agent or underlying platform.

• Explainer¹: The WG recommends the introduction to the spec as explanation of its purpose and use.

• Specification: https://www.w3.org/TR/digital-credentials/

• WPT Tests: https://github.com/web-platform-tests/wpt/tree/master/digital-credentials

• User research:

• Security and Privacy self-review²: https://github.com/w3c-fedid/digital-credentials/blob/main/horizontal-reviews/security-privacy.md

• GitHub repo: https://github.com/w3c-fedid/digital-credentials/

• Primary contacts:

• Primary standards group developing this feature: W3C

• Group intended to standardize this work: same

• Incubation and standards groups that have discussed the design:

Further details:

• I have reviewed the TAG's Web Platform Design Principles
• Previous early design review, if any: N/A
• Relevant time constraints or deadlines: Apple has announced the API will ship in iOS 26 in September and Chrome is aiming to ship in version 140 in September, but both implementers have indicated flexibility in evolving with the specification where possible.
