@gr5org - That's not really a solution, that's just a new security issue. If you do happen to lose track of your backup codes, they don't give much away, and they only allow one-time access to your account. If during those accesses they chose to remove, or change, your 2FA settings, you would know about it. If instead you lose the information necessary to generate 2FA codes for your account, they have potentially unlimited access to your account, and won't have to change anything to maintain access. This would allow an attacker to monitor your account until a moment of maximum impact to cause damage (steal your money). With a one-time backup code (or set of) they have a small window of access to your account, and limited ability to keep tabs on it, with the ability to generate they have everything they need.
