How to Hide API Keys During Screen Sharing (2026 Guide)

Short answer

Hide API keys by combining auto-detection, element-level blur, and safer sharing mode before every session.

Direct answer

To hide API keys during screen sharing, pre-scan for secret patterns, blur sensitive fields manually where needed, and share only a prepared window or tab.

Step-by-step

1. 1Identify where keys are visible: dashboard, terminal, and dev tools.
2. 2Run auto-blur for key/token patterns and verify all critical fields.
3. 3Start sharing from a prepared tab or window only.

FAQ

Where do API keys usually leak during demos?

Most leaks happen in environment pages, terminal logs, or request headers in browser dev tools.

Can auto-blur catch all key formats?

It catches common formats, but manual verification is still required for edge cases.

Should I share full desktop when coding?

No. Share only the required tab or window to reduce exposure scope.

API keys leak in ordinary moments

You do not leak secrets only in dramatic incidents. Most leaks happen in normal workflows:

• showing a Vercel environment page,
• opening Supabase project settings,
• checking AWS credentials,
• expanding a terminal error that includes token values.

If your session is recorded, that leak becomes persistent.

The three surfaces you must protect

1) Dashboard settings

Vercel, Supabase, Stripe, AWS, and other admin pages often expose key-like values or identifiers near copy buttons.

2) Terminal output

Build scripts and debug logs frequently print values from environment variables.

3) Dev tools

Network and storage views can expose JWTs and bearer tokens.

Fast workflow to blur API keys

1. Run auto-blur with developer-secret patterns enabled.
2. Manually blur any visible key fields that remain.
3. Keep a checklist for repeated demos by platform.
