I already said it's a backup copy of the key, obviously nobody is expected to type in from a printout in day-to-day operations. Our experiences must differ substantially here. I've worked at a few startups over the past two decades, and I would not trust any of the finance people from any of those companies to practice good operational security or be reliably available as a cog in a critical real-time operational path. They were consistently the kinds of people who would treat a locked filing cabinet behind a locked office door as the height of security, and in many cases left important private documents like checks revealing salaries completely insecure, face down on recipients unattended desks. They have often been the staff least reliably in the office, and least accessible at any given moment - especially after hours or on weekends. In my view it's just exposing the key to more risk of getting left out or forgotten in a poorly secured, often unattended filing cabinet behind trivially picked locks. Just to make it available through someone frequently absent on vacation. Good thing the security will likely suck, because you'll probably have to pick those locks when you need the copy and the CFO is skiing down a mountain. This is an issue for the department in charge of performing backups and restores. They will already have access to the key to do the job, and they need to be accessible in times of crisis. Why wouldn't the COO be the right person if operations is in charge of disaster recovery? It's their ass on the line when they can't do a restore on the weekend. The CFO and the entire finance department has zero expectation of being available after hours or on holidays.
