Import from LastPass, Apple, or Google with one click, then let humans and AI agents use your accounts on your behalf.","body":"### Explainer Video\n\nhttps://www.youtube.com/watch?v=lug9O3BK7ok\n\nMultifactor is building the future of zero-trust authentication, authorization, and auditing for AI agents.\n\nToday, we’re excited to launch the best new way to securely share online accounts with humans and AI agents alike. Multifactor turns any online account into a “checkpoint link,” making secure and revocable account sharing as easy as sharing a Google doc.\n\n### FAQs\n\n**🧑‍💻 Who are we?**\\\nVivek Nair, co-founder \u0026 CEO, is a Ph.D. computer scientist and former CIA officer. Colin Roberts, co-founder \u0026 CTO, is a Ph.D. mathematician and former NASA scientist. We’re both passionate about usable security, with over a decade of cybersecurity experience.\n\n**🤔 What can I use it for?**\\\nOne of our investors uses the app to share email and calendar access with a rotating team of personal assistants without worrying about unauthorized edits.\\\nOur friend who is a financial advisor uses Multifactor to manage their clients’ brokerage accounts without needing their passwords.\\\nOur colleague uses Multifactor to share Instacart and Netflix accounts with her roommates while being able to easily add and remove people.\n\n**⏳ Why now?**\\\nWith increasing adoption of passkeys, biometrics, and MFA, accounts are getting more secure but harder than ever to share. Sharing conventional accounts with non-human actors (like AI agents) is also an emerging need that current solutions fail to address.\n\n**🔜 What’s next?**\\\nMulti, our AI assistant specializing in secure online account use, is right around the corner, with API access for developers coming shortly thereafter. The version you’re using today will always be free, but an enterprise plan with advanced features is coming soon.\n\nOur world-class \"account manager\" that allows agents to securely use online accounts on your behalf is just the start—our patented AI security technology seamlessly integrates with existing agentic software to thwart attacks like prompt injection, so CISOs and end users alike can breathe a sigh of relief, without slowing the pace of AI adoption.\n\n### Get Started\n\n* On the Web: https://app.multifactor.com\n* On iOS: https://apps.apple.com/us/app/multifactor-account-manager/id6753222030?platform=iphone\n* On Android: [https://play.google.com/store/apps/details?id=com.multifactor.app](https://play.google.com/store/apps/details?id=com.multifactor.app\u0026ref=producthunt)\n* On Mac: https://apps.apple.com/us/app/multifactor-account-manager/id6753222030?platform=mac\n* On Windows: https://apps.microsoft.com/detail/9njxfnh5xb8d?hl=en-US\u0026gl=US\n* On Chrome: https://chromewebstore.google.com/detail/multifactor/kbmlcdbnkedhffonmapkcglkllgdelhm\n\n### Demo Videos\n\nSharing accounts just by sending a link, **without** ever actually sharing the passwords.
