Passport Prime is Human Authority Hardware. Secure your Bitcoin, codes, wallets, agents, and apps built with KeyOS SDK. Nothing happens without your approval.

Assembled in USA
It's time for a new foundation. Not a new start. Legacy Mode is live on Passport, keep every account you already have, on code anyone can inspect. Switch to open source hardware and software while keeping your existing accounts for supported assets. Here’s how. 🧵

Your login codes shouldn't have to live on your phone. Passport Prime keeps your 2FA codes offline, on dedicated hardware you control. With KeyOS 1.4.0, there are more ways to bring your existing accounts across, including bulk imports from Google, Aegis and Proton Authenticator. Import your accounts, then generate the codes you need directly on Passport Prime, without an internet connection. Your email, work accounts and digital identity deserve protection, too.

Three NFC key cards, each in its own Faraday sleeve. A USB-C cable. A warranty booklet. Every detail considered. A 3.5" touchscreen. Arctic Copper or Midnight Bronze. Assembled in the USA. We're not the kind of company that throws hardware in a plastic bag.

FAQ: Do I have to install third-party apps on Passport Prime? No. It comes with only Bitcoin & security apps pre-installed. You choose what to install, nothing is forced. Your device, your rules.

Your Bitcoin is only one part of your digital life. Your email holds password resets. Your cloud accounts hold private documents. Your social accounts carry your identity and reputation. Those deserve protection, too. Passport Prime goes beyond securing your Bitcoin. It can also act as a hardware security key for compatible services over USB or NFC. What does that mean in practice? You register Passport Prime with a supported account. When you sign in using that security key, you connect it over USB or tap it via NFC, then approve the login on the device. That puts a deliberate, physical step into an important login, using hardware you control.

"We reimplemented the interfaces that Ledger's open source apps use to talk to BOLOS, its operating system," said Ken Carpenter, cofounder and CTO of Foundation. "That includes cryptographic operations, screen rendering, and USB communication. We can compile the existing app code for Passport and run it on KeyOS, without running Ledger's proprietary operating system.” Thanks to @Benzinga for covering our latest announcement, read the full article below. benzinga.com/content/6179216…

Before trusting a device with your Bitcoin and security keys, what should you be able to inspect? Start with three things: → Source code Can independent developers examine how the software works? Security claims carry more weight when people outside the company can scrutinise the implementation. → Security models What threats is the device designed to protect against? What assumptions does it make? Understanding the boundaries matters as much as understanding the protections. → Independent audits Who reviewed the device, what did they examine, and what did they find? Look for the scope, findings and the company’s response, not just an “audited” badge. Foundation publishes source code, security models, and independent audit reports alongside our responses. You shouldn’t need to rely on a product page alone. Explore the details: foundation.xyz/security

This is why smartphones and computers can never serve as a root of trust for AI security & human authority. Tens of millions of lines of code. No formal verification. Each time a frontier model is released, it will be whack-a-mole to fix newfound vulnerabilities.
Urgent security advisory for iOS users! Install the latest iOS update immediately. Security researchers report that financially motivated attackers are now using a complete, in-the-wild exploit chain that can quietly steal cryptocurrency private keys and mnemonic seed phrases from iPhones. The reported attack begins when a target is socially engineered into opening a malicious page in Safari. That page is said to abuse a memory-corruption flaw in WebKit / JavaScriptCore to gain arbitrary read/write access from JavaScript, then bypass Pointer Authentication Codes (PAC) to run native code, break out of the WebContent sandbox, and escalate to kernel/root privileges. With that access, attackers can pull data from the device Keychain and from local crypto wallet apps. The claimed impact range is iOS 13 through iOS 26.5; that range has not been independently confirmed in full. Until more is known, treat any unpatched device as potentially exposed and update as soon as a newer build is available. Also avoid untrusted links in Safari, especially if you keep wallet keys or seed phrases on the phone.

Keep what you’ve built. Change the foundation. Moving to open source shouldn’t mean rebuilding your entire setup from scratch. Foundation.xyz/switch

We said you could build apps for Passport Prime. Someone did the maths. 🧮 A calculator, running on KeyOS. Simple? Yes. Useful? Also yes. What would you build next?
