Storing Only Extended Public Key on Coldcard Q | Security Concerns Grow Among Users
A rising number of Coldcard Q users are questioning the device's security after a recent online discussion sparked concerns about storing seed phrases. As Bitcoin ATMs gain popularity, users wonder whether it’s possible to store only an extended public key (xpub) while keeping private keys off the device.
This discussion comes as users share their experiences with using the Coldcard Q in various Bitcoin ATM transactions. The allure of purchasing Bitcoin via these machines is enticing, but many feel uneasy about carrying their seed phrases on the device itself. There’s a notable push towards increased security without sacrificing convenience.
The Significance of Keeping Private Keys Secure
The Coldcard Q, known for its large display, offers a clean interface for managing Bitcoin transactions. However, the need for enhanced security is apparent. Some users express frustration over the requirement to connect devices to the internet to conduct transactions, fearing potential data breaches.
One user, who prefers not to connect their wallet to the internet, noted: "It’s essential to keep my wallet separate to avoid KYC implications with my Bitcoin purchases." This highlights a broader theme among users advocating for privacy and security within digital currency transactions. While the Coldcard Q is designed to facilitate transactions, users grapple with the best practices for managing their keys without compromising safety.
Community Sentiment and Recommendations
Responses in the community showcase a mix of skepticism and innovative suggestions. Many believe that alternative solutions, such as utilizing a phone wallet for xpubs, may be more appropriate, considering the data security loopholes associated with connecting Coldcard devices online.
"You could just print the target address for your next ATM withdrawal on paper…" suggests one community member, emphasizing a strategy that avoids tech dependencies altogether:
Incorporating paper QR codes can ensure no private keys are exposed during transactions.
Engaging in discussions about convenience vs. security remains crucial, considering recent trends in Bitcoin ATMs.
The community's dialogue reflects a strong desire for enhanced security features in future device updates.
