We cleared four days, cancelled every meeting, gave five engineers unlimited agent credits, and made everyone demo live on Thursday. multifactor.com/blog/lock-in…

6 months ago, we met a team that was remarkably well aligned with our agentic security vision. Today, we're joining forces. We've officially acquired Keypo, Inc., and its founder Dave Blumenfeld is joining us as Founding Engineer, bringing his work on secure enclaves directly into our platform.

The Multifactor Challenge is live! Anyone with Multifactor can now use our Checkpoint link to log into our business checking account on Meow, where we’ve stashed $1 million in VC funding. Every dollar we’ve received from YC is in there, but we’re not worried. Our Checkpoint account-sharing system has disabled transfers and withdrawals, and our credentials are protected by Multifactor’s post-quantum-secure encryption. If the laws of math don’t fail us, our funding will be just fine. Check out the video below for the link, and be sure to follow us here for live updates.

Securely sharing any online account with AI agents. Can your password manager do that?

One-click logins to any site, on any device. Can your password manager do that?

Instantly revoke shared accounts, without having to change your passwords. Can your password manager do that?

Sharing accounts just by sending a link, *without* ever actually sharing the passwords. Can your password manager do that?

Watch this space! One week from today, we'll be putting Multifactor through the ultimate stress test. We're going to publish a link that lets *anyone* log in to our company's primary business checking account. $1M of funding — basically every dollar we have raised — will be on the line. But standing between us and disaster will be Checkpoint, our secure link-based account sharing system! Will someone try to take the money? No doubt. Will they succeed? The math says no way—and so do we. Stay tuned for more details.

We are incredibly grateful for (and overwhelmed by) the surge of recent interest in Multifactor! In the past 48 hours, hundreds of new users have signed up for Multifactor and propelled us to a #1 spot on @ProductHunt, even on a day with four YC launches. Your support and feedback mean the world to us as we continue to refine the product. Onwards and upwards! 🚀
