Twitter just boosted its security with a new two-factor login method. The new option, which was announced in the form of a YouTube video, oddly enough, allows users to require a verification code each time they log in. Once this is enabled, Twitter will send a code to your phone each time you log in from the website or third-party apps. You'll need to type in that temporary code to access your account. It's a process many of us are already familiar with -- online banking, corporate intranet sites and services like Evernote offer similar two-factor authentication options to their users. It's not clear when the new feature will roll out (it hasn't hit our account just yet), but once it's available, setup appears to be straightforward. You can see how it works in the video just past the break.
