Cloudflare Access can protect a Worker or all Workers at account scope

Cloudflare added Worker-level and account-wide Access protection on 14 August 2026, allowing one Access policy to follow a Worker across its domains and preview URLs or to make all existing and newly created Workers require sign-in by default.

Previous state

Protecting a Worker across routes, Custom Domains and workers.dev URLs required adding and maintaining those hostnames individually in an Access application, and there was no announced account-wide default for all Workers.

Current state

Access policies can attach directly to a Worker across associated domains and preview URLs, and an account-wide setting can require sign-in for all existing and newly created Workers by default with Worker-level bypass exceptions.

Who needs to care

Cloudflare Workers administrators using Access to protect Worker routes, Custom Domains, workers.dev URLs and preview deployments.

What to do

Choose Worker-level or account-wide Access scope deliberately, review sign-in policies and bypass exceptions, and test preview and production behavior before changing access defaults.

What the source does not prove

The source proves that Worker-level and account-wide Access protection are available. It does not mean every customer Worker was automatically made private; administrators choose whether to enable the controls and may configure Worker-level bypasses.
