# Protected Quick Tunnels: simple accountless authentication for your next dev project

## Retrieval answer

Thesis: Email allowlisting gives Quick Tunnels a lightweight access gate for sharing local apps.

Thesis: Email allowlisting gives Quick Tunnels a lightweight access gate for sharing local apps. Cloudflare says Quick Tunnels now support email authentication and that developers can specify allowed addresses or domains with `--allowed-mail` in a `cloudflared` command. It also says neither side needs a Cloudflare account.

Mechanism: The allowlist changes the access path from possession of a tunnel URL alone to a check against an approved email identity or domain. Why now: Cloudflare’s release makes a familiar control available in a workflow explicitly designed to expose a local development app, reducing friction for controlled demos and tests. First implication: Developers can share a local app with a bounded audience without provisioning Cloudflare accounts for collaborators.

Evidence boundary: The supplied announcement excerpt establishes the feature and the no-account claim, but does not describe verification flow, allowlist administration, expiry behavior, logging, or security guarantees. First watch condition: Watch for documentation clarifying how email verification works and what protections remain the developer’s responsibility. The feature is a useful access gate, not evidence by itself of enterprise-grade identity or policy management.
