Feature-Policy: microphone

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTTP Feature-Policy header microphone directive controls whether the current document is allowed to use audio input devices. When this policy is enabled, the Promise returned by MediaDevices.getUserMedia() will reject with a NotAllowedError.

Syntax

Feature-Policy: microphone <allowlist>;
<allowlist>

The allowlist is a list of origins that takes one of the following values:

  • *: The feature is allowed by default in top-level browsing contexts and all nested browsing contexts (iframes).
  • 'self': (Default) The feature is allowed by default in top-level browsing contexts and in nested browsing contexts (iframes) in the same origin. The feature is not allowed in cross-origin documents in nested browsing contexts.
  • 'none': The feature is disabled in top-level and nested browsing contexts.
  • <origin(s)>: The feature is allowed for specific origins (for example, https://example.com). Origins should be separated by a space.

The values * (enable for all origins) or 'none' (disable for all origins) may only be used alone, while 'self' may be used with one or more origins.

The default value is 'self'.
