Is 2FA on the table for the wallet, using either Google Authenticator or Authy maybe?
Is this a possibility and is it been considered?
I considered this in another project, there are fundamental problems with it. It means you need a centralized solution. For now if you want 2fa an exchange is really the best option. (This was one of the first ideas I wanted some time ago, but the centralization is really a non starter for it)
