Does this replace CSP?
No. CSP controls *resources* (like scripts), while Permissions Policy controls *browser features* (like the camera).

Practical Application & Code Integration
Use-Case Context
The Permissions Policy (formerly Feature Policy) explicitly defines which browser features (Camera, Microphone, Geolocation, WebUSB) are allowed to be used by your application or third-party iframes. This locks down privacy vulnerabilities, ensuring an embedded YouTube video or ad cannot silently access the user's camera.
Express.js Permissions Header
const express = require('express');
const app = express();
app.use((req, res, next) => {
// Deny all access to camera, microphone, and geolocation
res.setHeader('Permissions-Policy', 'camera=(), microphone=(), geolocation=()');
next();
});03
Common Questions About Permissions Policy Generator
Why should I disable features I'm not using?
It's a security best practice (Principle of Least Privilege). If your site is compromised, the attacker still won't be able to access the user's mic if it's disabled via header.
