Sign in on devices where signing in is a pain.

Powered by @Clerk’s OAuth Device Authorization Grant.

[Clerk @clerk]

Bundle IDs, Team IDs, Associated Domains, entitlements. The Clerk CLI now handles all of it for iOS and macOS.

Ask your agent: "Add Clerk to my iOS app using the Clerk CLI."

[Clerk @clerk]

Now agents can click through your dashboard.

Agent Readiness update for you - Nov 6

Here's what shipped 🚢
1. Browser sessions for agents
2. Step-up permissions for your MCP tools

Native mobile vs web have very different attack vectors, so it's common to want different session lifetimes on each

Now you can 👇

[Mike Pitre @mikepitre_]

native apps don't have the same threats as web apps. shorter sessions might make sense in a browser, but on mobile they mostly just sign real users out. now you can set them separately

[Clerk @clerk]

Keeping web sessions short shouldn't mean signing mobile users out every week.

Clerk now lets native sessions have their own maximum lifetime. Set the lifetime that fits each platform, from 5 minutes to 10 years.

[Mike Pitre @mikepitre_]

this is one of those features you don't think about until the day you really need it

[Clerk @clerk]

Sometimes your users just need to update.

Set a minimum version for your iOS and Android apps with Clerk, and anyone below it gets an update screen that links to the App Store or Google Play. They're still signed in when they come back.

[Robert Soriano @wobsoriano]

Let users sign in and sign up on @Clerk's Account Portal, right from your native app.

Hosted auth is available in the Expo, iOS, and Android SDKs.

[Expo @expo]

We just wrapped Build North in Toronto! Our ten-day hackathon with @Georgian_io!

Our winning team built GreenLens, an app that puts an agentic plant doctor in your pocket

Built with the Expo SDK and Expo modules for LiDAR and RealityKit, with @Clerk for sign-in and @SurrealDB for the data

If you're building a really cool app, we'd love to see it!

Exactly 12 hours left to submit to the Expo App Awards: https://t.co/nMjf88EA04

Auth for MCP is @clerk's new Auth for React

We launched it 15 months ago, but it didn't start growing 13% WoW until 8 weeks ago 🤯. We haven't seen a growth rate like this since 2023

[Clerk @clerk]

Agent Readiness update for Clerk - Oct 21

Every week, we make it easier for agents to launch and run businesses with Clerk.

Here's what we shipped last week 🚢
1. Ops-focused MCP tools
2. @bot plugin
3. Misc. AX improvements

More info in 🧵

[Clerk @clerk]

Death to clickops 💀. Our new @bot plugin lets you stay out of our dashboard

[Nate @NateWatkin]

New logo alert

[Mike Pitre @mikepitre_]

if you've wanted to let users connect their agents to your app without building all the auth stuff yourself, @clerk does that now

[Clerk @clerk]

Agent Readiness update for You - Oct 16

Today, we introduced an "Agents" section to your app's config.

There, you'll find the setup to add auth to your MCP server, along with an agent prompt to help build a new MCP server.

[Braden Sidoti @bsinthewild]

We've seen a massive increase in both the number and sophistication of fraud attacks. CAPTCHAs and WAFs are not nearly enough.

Clerk Protect (a @clerk product) is starting to roll out generally.. This is just the first release of many.

If your application is under attack, DM me. We can most likely help. Clerk Protect will work with any auth provider, but it will be at toggle away for existing clerk customers.

Super excited to make bad actors, sad actors.

Authentication has no business being this fun.

Meet the Clerk van. 🚐

[Jeff Escalante @jescalan]

Fun fact - @clerk now has a backup email provider under the hood, so that if our primary email provider has an outage, your auth is still not impacted. Both providers use entirely different infrastructures, so an AWS or GCP outage can't take them both down.

It takes a ton of work to get features like this in place, the many subtle differences between two different providers add up across your customer-facing logs and codebase surfaces. I'm not aware of any other providers that do this.

Most people don't know about it at all. It's not a big flashy exciting feature, but often times invisible reliability work is the most important work 🤝

[Mike Pitre @mikepitre_]

Remember when people said @clerk was just for Next.js? The Clerk mobile team would like a word 🚀

[Colin Sidoti @tweetsbycolin]

Clerk now handles auth for over 10x the number of mobile apps versus the beginning of the year 🚀

[Hamed Bahram @HaamedBahram]

@v0 now has one-click integrations for auth, email, search, and databases.

I asked it to add @clerk auth to my app. It wired up the SDK and middleware, provisioned a Clerk app, and brought in the keys. Then I published to Vercel.

Prompt to live app with auth 👇🏼

[Colin Sidoti @tweetsbycolin]

Daily active MCP servers managed by @clerk has grown 13.7% WoW for the last 5 weeks (forgive the data hole)

Clerk is the easiest way to build MCP alongside traditional auth
