Question around public key encrypting 2FA secrets

[johnnynanjiang]

Hi @oceans404,

Nice work on Wallet OTP, it is exactly what I'm looking for, a decentralized version of 2FA.

Just one question, since 2FA secrets are encrypted by the public key, and decrypted by the private key. In the worst case of the private key being exposed, the hacker could go decrypt and get the 2FA secrets.

Is this a probable scenario?

Thanks and regards,
