We already have language on deviceId: Since [deviceId](https://w3c.github.io/mediacapture-main/getusermedia.html#dom-mediadeviceinfo-deviceid) may persist across browsing sessions and to reduce its potential as a fingerprinting mechanism, [deviceId](https://w3c.github.io/mediacapture-main/getusermedia.html#dom-mediadeviceinfo-deviceid) is to be treated as other persistent storage mechanisms such as cookies [[COOKIES](https://w3c.github.io/mediacapture-main/getusermedia.html#bib-cookies)], in that User Agents MUST NOT persist device identifiers for sites that are blocked from using cookies, and User Agents MUST rotate per-origin device identifiers when other persistent storage are cleared. So the question is if "other persistent storage are cleared" covers the Clear-Site-Data header. If it does, it's an implementation bug. -- GitHub Notification of comment by alvestrand Please view or discuss this issue at https://github.com/w3c/mediacapture-main/issues/836#issuecomment-1049988688 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-configReceived on Thursday, 24 February 2022 15:42:08 UTC
