Auto Blur

Hides passwords, API keys, credit cards and emails on any webpage. 100% local — nothing leaves your computer.

Stop leaking secrets on screen shares. Auto Blur is a Chrome extension that finds sensitive data on any webpage - passwords, API keys, credit card numbers, emails, tokens - and hides them in real time, before anyone else can see. Runs 100% on your computer. No account, no servers, no tracking. WHAT IT HIDES • Email addresses • Phone numbers • API keys (Stripe, bearer tokens, generic) • JWTs • AWS access keys • Credit card numbers (Visa, MC, Amex, Discover) • Private keys (PEM blocks) • GitHub tokens (classic + fine-grained) • Inline passwords and secrets (password: …, client_secret: …) HOW IT WORKS • Install, and it starts working immediately on every site you visit. • Sensitive values are hidden behind a soft blur. Click any one to peek for 3 seconds, then it re-hides itself. • Adjust the blur intensity from the popup. Toggle per-site if needed. PANIC MODE (Pro) Someone walks up mid-screenshare? Hit Option+Shift+B (or Alt+Shift+B on Windows) and the entire page blurs instantly. Hit it again to restore. CUSTOM RULES (Pro) Add your own regex patterns — employee IDs, internal URLs, project codenames, anything else you don't want flashing on screen. PER-SITE CONTROLS (Pro) Pause or disable Auto Blur on specific domains when you actually need to see the values. Works across all subdomains and iframes. PRIVACY BY DESIGN • No account. Install and use. • No servers for the extension. Nothing to phone home to. • No tracking. Not even usage metrics. • Allowlist is stored as an irreversible fingerprint — not even we could recover what you added. Free forever for the core pattern-detection features. Pro features available via a token (details at the link below). Suitable for developers, designers, support agents, or anyone who screen-shares code, email, or dashboards.
