Twitter users can use a new app for iOS and Android devices to better protect their social network account from hackers and other attackers. The update features two-step verification.
When activated, Twitter sends a confirmation request to the smartphone at every login attempt on a browser or other device. The user doesn’t get access to their account until approving the request.
This new function is found under Security in Settings. A 12-digit back-up code is generated upon activation and this code should be stored in a safe place. The code is needed to access your account when you don’t have your phone.
Double verification with Twitter was previously only available via text messages.
