Foundation Passport 2 review for 2026 — the open-source, Bitcoin-only, air-gapped hardware wallet with a full keyboard and color screen. Is it worth $199?
The Foundation Passport 2 is one of the most thoughtfully designed Bitcoin hardware wallets on the market — open-source, built by a small US-based team, and unapologetically focused on Bitcoin only. If you care about supply chain integrity and want a device that's never had its security architecture compromised by adding altcoin support, the Passport 2 deserves your attention.
The Passport 2 (sometimes called "Passport Batch 2") is Foundation's second-generation hardware wallet, released after the original Passport. It is:
Price: $199 (with MicroSD card included)

The Passport 2's physical design is its most distinctive feature.
The Passport 2 includes a removable, rechargeable battery — a rarity in hardware wallets. The battery means:
The Passport 2 uses a Microchip ATECC608A secure element for key storage — the same chip used in other premium wallets. Foundation pairs it with an MCU (STM32 microcontroller) to create a dual-chip architecture where neither chip alone has complete key access.
For additional trust, Passport 2 also includes a Nordic nRF52840 for Bluetooth (disabled by default and can be disabled permanently).
Passport 2 is designed for completely air-gapped operation:
No USB cable ever touches the device in this workflow. For paranoid security, this is ideal.
You can also transfer data via MicroSD card:
The included MicroSD card enables this workflow out of the box.
USB is also available for those who prefer it, but Foundation recommends air-gapped operation and the wallet is specifically designed for it.
Foundation's companion app, Envoy, is a Bitcoin wallet app for iOS and Android that connects to your Passport 2.
Envoy is a notable differentiator — many hardware wallets rely on third-party wallets. Foundation's integrated app is polished and designed for the Passport workflow.
Passport 2 also works with:
All Passport 2 firmware is publicly auditable. Foundation Devices actively encourages security researchers to review the code. This transparency is a significant trust advantage over closed-source alternatives.
Foundation is transparent about component sourcing. They purchase components directly from distributors (not gray market), and the open-source hardware design allows verification of what's in the device.
The Passport verifies its own firmware integrity on every boot. If tampered firmware is detected, the device alerts you.
Passport uses a "device word" — a unique word assigned to your device during setup. This word appears on the device's boot screen. Phishing attacks often try to get you to enter your seed into a fake device — the anti-phishing word helps verify you're on your real device.

Consider alternatives if:
The Foundation Passport 2 is the most polished Bitcoin-only hardware wallet for users who prioritize open-source transparency and air-gapped operation. The keyboard and large screen make it genuinely pleasant to use — a rare quality in hardware wallets. At $199, it's priced above Coldcard but justified by the superior UX and integrated Envoy app.
If you're a Bitcoin-only holder looking for a Coldcard alternative with better usability, the Passport 2 is the top recommendation.
Is Foundation Passport 2 better than Coldcard? Depends on your priorities. Coldcard has a longer track record and is favored by hardcore Bitcoin developers. Passport 2 has better UX, full open-source hardware, and a superior companion app. Both are excellent.
Can Passport 2 hold Ethereum? No. Foundation Devices is Bitcoin-only. If you hold ETH or other altcoins, you need a different wallet.
How does Passport 2 handle multisig? Passport 2 fully supports multisig through Sparrow Wallet and Specter. It can be used as one of 2-of-3 (or any n-of-m) signers in a multisig setup.
What happens if Foundation Devices goes out of business? Because the firmware is fully open-source, the community can continue maintaining it. Your Bitcoin is always recoverable with your seed phrase using any BIP-39-compatible wallet, regardless of what happens to Foundation.
Does Passport 2 connect to Bluetooth? The hardware includes a Bluetooth chip but it's disabled by default. Users who want zero wireless transmission can follow Foundation's instructions to permanently disable Bluetooth.
