Cloudflare adds email-based access control to Quick Tunnels
Cloudflare now lets developers restrict who can use Quick Tunnels links by email address or domain, adding a simple but critical gate to its previously wide-open tool for exposing local apps. With the new version of cloudflared, you add the --allowed-mail flag, and only invited users get in after confirming their email with a one-time code. No Cloudflare account needed on either side.
- Developers can now gate Quick Tunnels by email or domain
- Visitors verify identity with a one-time email code
- No Cloudflare account required for either side
- AI agents widely use Quick Tunnels for code demos
- Update reduces risk of accidental public exposure
