Bringing authentication and identification to Workers through Mutual TLS

Cloudflare is set to introduce mutual TLS authentication support in its Workers product, allowing workers to send outbound requests through a mutually authenticated channel. This feature will provide an additional layer of security for applications built on Workers by enabling two-way authentication between the client and server. The implementation of mutual TLS will allow users to upload their own client certificates and attach them in fetch() requests within a worker, providing granularity at both the worker and request levels. This highly requested feature is expected to be launched soon, making it easier for developers to use Cloudflare as their platform for building applications.
