One of the safest ways to secure transactions, is to attach two factor authentication, or BIOMETRIC authentication in order to transfer funds outside of Steemit.

A lot of people might say that this limits privacy, but isn't the security of your net worth worthy of a tiny interval of authentication? ;)

As of now, the "keys" that allow transfering of funds are susceptible to a host of attacks, such as man in the middle attacks, or keylogging (backdoor, remote access tool) attacks. Adding a two factor authenticator could make the integrity of Steemit account transactions (especially when it comes time to transfer funds outside of Steemit) much more secure.

(The 2FA could even be anonymous, such as with a Yubico Key, or a printed "one time" grid).
