Twitter Now Allows Two-Factor Authentication Via Third Party

[engine]

Obviously, you all use two-factor authentication on your twitter account, don't you? If not, why not?
In addition to using SMS two-factor authentication, twitter now allows the option of two-factor authentication via a third-party app, such as Google Authenticator, Duo Mobile, Authy, or similar, if installed on your mobile device.

It's about time... 2FA via SMS is really not secure. I wonder why it took them so long to make this change.

Now I'm off to change all of my accounts.
