BlurSecrets
2026 · Chrome Extension · Privacy
A privacy-first Chrome extension that automatically blurs passwords, API keys, tokens and personal data so screen shares only capture blurred pixels.
Overview
BlurSecrets keeps sensitive information off your screen shares and recordings. It continuously scans the page — including content loaded later by React or Angular apps — and blurs anything that looks secret, right in the page, so Zoom, Meet, Teams or OBS only ever capture blurred pixels.
Beyond automatic detection, you can point at any element to blur it permanently on that page, add your own patterns, and click a blurred value to reveal it for three seconds before it re-blurs itself.
The Problem
One careless tab during a screen share can leak an API key, password or customer data. Remembering to hide everything manually before every call is unreliable.
