Fenton explained both sides of the effectiveness problem.
Twitter wants to make one thing clear to the media -- it takes two to protect Twitter accounts.
Twitter sent out a warning memo asking media groups to do their part to protect passwords after several high-profile accounts were hacked.
Here's a rundown of what two-factor authentication is, how it can work for you, and what its limitations are.
Two-factor authentication adds a second level of authentication to an account log-in. When you use your credit card and you must enter in your ZIP code to confirm a charge, that's an example of 2FA in action.
It definitely adds an extra step to your log-in process, and depending on how the account vendor, such as Twitter, has implemented it, it can be a minor inconvenience or a major pain.
Much also depends on your patience and your willingness to spend the extra time to ensure a higher level of security.
Oberheide said that many of his customers start off thinking that implementing 2FA will be expensive or hard to use, but often find that their experience with it is the opposite.
"I think that will come faster in the consumer space because they're not dealing with all this cruft from the legacy of 2FA from the '80s," he said.
