[Security] Support security keys (such as Yubikey) for administering settings/transations

Add Security key (Such as Yubikey) support for things like:

  • Viewing your private key
  • Changing key settings like your password, or address whitelisting (need to add this feature too!)
  • Sending transactions

Using a physical security key will greatly improve security, especially for those who don’t have a hardware wallet yet.
It helps secure your private key settings and allows you to lock address whitelisting settings too.
It reduces risk of being held at gunpoint and forced to transfer your crypto against your will.

i.e. You are unable to make the transfer without your Yubikey which is at home,
Showing a clear screen “Unable to access without Security Key” might help deter assailants)

agreed or integration with Google authenticator for those features. I had a metamask wallet compromised (by my own fault) but some 2 factor authentication would have saved me from myself.
