EFF, Parker Higgins: “Twitter rolled out two-factor authentication last week, joining a growing group of tech companies to support the important security feature. Two-factor authentication can help mitigate the damage of a password breach or phishing attack…Twitter has named its two-factor authentication system “Login Verification,” and its announcement provides a straightforward guide on how and why to use it. It directs you toyour account’s settings page, where enabling the option is basically a one-click affair.”
