🔐 Single-Sig Spending Policies & 📱2FA!
You can now reconfigure your existing COLDCARD with a policy📑, so it will refuse to sign transactions that are too large, too frequent, or sent to an address not on your whitelist
We have also found a way to support **2FA authentication** using the usual phone apps (RFC 6238). If that's enabled, you will not be able to spend using your #COLDCARD unless you also have your phone and provide the correct #GoogleAuthenticator 6-digit numeric code.
Added file rename, Explorer is now offered for transactions of all sizes, NFC improvement, Added @BullBitcoin_, and many other fixes and improvements!

Discussion
The tap signer doesn’t have a screen, so if the application / device that is asking for the tap signer to sign is compromised, you can not valid the transaction details on the hardware wallet. It will blindly sign any transaction given to it.
