I am able to use the Passkey successfully, but when I use IB Gateway (API connect) with 3rd party software on remote desktop (Server located in NY) to execute the orders, the windows only pop-up states that a Physical Passkey USB is required. No other options like Windows Hello / or Mobile Passkey (QR Scanning) to be provided. So I did not trade using that platform for few days already. I have contacted the technical support, still awaiting their responses, been waiting for 2 days already....Any thoughts?

bruh, I gotta start digging up old USB sticks at home and resell it on eBay

If this keeps going, a 32MB USB Stick will be $100 next year.

In IBKR, after you typed username and password, the next step is passkey authentication. That made passkey the second factor. My passkey is the IB Key, where I had to approve in IBKR mobile app using Face ID. Recently, I added YubiKey so, I have a choice to use IB Key or YubiKey as the second factor.
If I login via Chrome on the desktop, I have to plug in YubiKey in the USB to authenticate after username/password.
If I’m using IBKR mobile, then I need to touch the YubiKey behind my iPhone (via NFC reader) to proceed.
I don’t see how this is creating the problem you described. Using the same analogy, there’s two doors (one after the other) and no window.

Most laptops charge via USB c so you can just buy a laptop battery pack while it sits in your bag if you’d like

Just boot an airgapped laptop from a USB stick and use /dev/rand with some extra entropy from mouse and keyboard. Also known as `ssh-keygen`.
When was the last time someone had their SSH key or certificate hacked by an entropy attack?

# Could Jade Offer a More Flexible Private Key Backup Model?
I doubt it, but maybe you are already working on something like this, especially since Coldcard’s seed handling is not ideal.
Since Jade does not use a secure element chip, could it be possible to keep some private key material temporarily in RAM and have an encrypted backup stored on a USB drive? (coldcard can save 30 privat keys)
The idea would be to have a more flexible recovery option without depending on one hardware wallet manufacturer forever. Companies can disappear, and it would be good to have a long-term backup strategy.
Do you think something like this could be implemented?

Stupid question as I know nothing about this. Is it better to get a low budget cold wallet that only has a USB connect? Is it Bluetooth that was the weakness in that recent hack? I would like to buy, just hate the idea of some human taking it.
