Since security is so important, we wanted to be transparent and share how we store secret keys and authentication information. I will note, it is extremely difficult to secure anything, and if you are holding a large amount of cryptocurrency, you should do so on a cold-storage wallet. If it is a particularly massive amount, then generate your wallet inside a Faraday Cage should someone try and Van Eck phreak you.
Looking forward to any thoughts or feedback.
