Now, to edit this, you need to understand how exactly the OTP is being generated, so go to the page.js file present in the "generator" sub-directory of "src/app" and also the two JS files in components sub-directory make your changes there. Till now the QR code generated is raw, that is, if someone gets hold of the OTP then they directly gets access to the QR so encrypt it so that even if someone gets it they don't get the OTP. Apply the encryption-decryption in such a way that only the receiver can decode the QR code.
