#COLDCARD Firmware Release 1.3.4Q & 5.4.4Mk4 🍄⏫
Read the complete release and upgrade here 📁 https://blog.coinkite.com/spending-policy
🔐 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!

This is amazing! Makes me feel much more comfortable using my Q as a single sig and not using multisig.
Unfortunately I guess an attacker who got their hands on the Q would be able to see my entire balance, even if it can't be transferred because of these policies.
Very cool update nonetheless!
Decoy pins still exist
Good point, I have yet to try that out.
nostr:npub12ctjk5lhxp6sks8x83gpk9sx3hvk5fz70uz4ze6uplkfs9lwjmsq2rc5ky has so many awesome features and I don't think I've even tried 10% of them yet
We hope to keep you busy for a long time :)
