Cloudflare Access added Passkeys support this week.

But have you actually used Cloudflare Access?

It's awesome. A few clicks and you can lock down any Worker to just you, your organization or whoever you choose.

Let me show you how, and then we'll also add a Passkey!

OpenAI Codex can now run on Durable Objects, the way it runs on your laptop.

[Cloudflare Developers @CloudflareDev]

@tamagoindoor Thanks for being part of Cloudflare for Startups. Let us know if we can help with the transition and work through the best path forward for your workloads.

[Cloudflare Developers @CloudflareDev]

@0xDidi Can't blame you for feeling that way. If you’d like to talk through the impact on your workloads, reply to the email and our team can work through the options with you.

[Cloudflare Developers @CloudflareDev]

@EZheng66099 @Cloudflare We hear you. This change puts you in a difficult situation, especially after you’ve built around these credits. If helpful, our team can review your account and workloads and suggest a path forward.

Cloudflare Access now supports passkeys.

Sign in to protected apps with a device passkey, security key, or password manager instead of a one-time PIN.

Admins pick which apps accept them.

You can automatically prompt passkeys on the login page.

Muse Ember from @AIatMeta is now available on @Cloudflare AI Gateway. With top tier speed and performance in its class, the model is efficient and a great fit for subagent workloads.

OK I did it.

Migrated WordPress to Emdash. goodbye $600 bluehost server I've had for 15 years.

307 posts
6.7gb photos
4 custom content types
5 custom page templates
15 custom fields
1 semi-complicated plugin converted and a handful of simple ones

Emdash skills moved it over, migrated off stylus(!) and it's pixel perfect on the front end.

The page speed score went from 52 to 75.

The Admin is fantastic as well - no problem for a WP user. Nice and fast

🔑 @Cloudflare Access now supports passkeys for protected apps and the App Launcher!!

Enroll once, then sign in with your device, security key, or password manager. 🛡️

If you're still using wrangler.jsonc for your workers, you're literally one command away from using a glorious cloudflare.config.ts

$ cf migrate

This gives you (read: your agents) access to ~3000 operations that you would normally use the dashboard for.

[Cloudflare Developers @CloudflareDev]

Spend less time wrestling with time.

Temporal, JavaScript’s modern date and time API, is available in Cloudflare Workers. Built-in time zone handling. Calendar-aware date math. Immutable values that won’t change unexpectedly.

Flip the temporal compatibility flag to take your time back.

Durable Object calls just got a little more durable

[Ashley Peacock @ashleypeacock]

Automatic retries for Durable Objects are here!

We are now retrying fetch and RPC calls to your Durable Objects automatically in the runtime, zero code changes needed.

We do have some config that allows you to make them more powerful, details below 👇

[Jilles Soeters @Jilles]

AI Gateway now supports model aliases! A model alias is a pool of models that your application calls by one name.

AI Gateway tries the models in the order you set and falls back to the next one if a request fails, or uses smart routing to choose a model for each request 🔥

New security vulnerability hits your radar. Should you patch now?

Zero Wire helps you work out what’s affected and what to do next. Confirmed facts, open questions, and remediation guidance — all in one place.

Introducing Zero Wire: a public vulnerability intelligence feed on @CloudflareRadar, bringing the clarity of a news wire service to critical security developments. https://t.co/pxMUvkdOgG

[Cloudflare Developers @CloudflareDev]

With the recent wave of vulnerability disclosures, it’s a good time to take a closer look at your own code.

Turn your coding agent into a team of security auditors with the open-source skill that seeded Cloudflare’s vulnerability discovery harness.

The 6 phase approach:
1. Map the codebase
2. Hunt for vulnerabilities
3. Challenge each candidate
4. Record the findings
5. Verify the findings
6. Report what’s confirmed, rejected, or still needs validation

Start your hunt here:
