Twitter announced last Tuesday that it will now be supporting universal two-factor (U2F) devices which are used as physical security keys for login verification.
The small keyring-sized devices boosts Twitter’s security since it is still possible for SMS verification codes to get intercepted. The associated key will also provide protection against fake Twitter pages that try to phish passwords and other sensitive information.
Twitter says that users that have their mobile numbers linked with their account will be able to set up the physical two-factor key. Those who already have the setting enabled can use Twitter’s support page to set up the new login verification method.
