Twitter starts with two-step verification

Message service Twitter has simplified its two-step verification system and made it more secure. Users can now set the security function without having to enter their mobile phone number.

With two-step verification, a code often sent to the user via SMS, which gives him access to service again. This method not only vulnerable to so-called sim swapping attacks, where the code sent to a hacker, but also encounters resistance from users for privacy reasons. For example, Twitter has already admitted that the numbers were used for advertising purposes.

Twitter Safety has announced through a tweet that the messaging service for two-step verification no longer requires the user’s telephone number. The function had become superfluous some time ago when Twitter came up with a verification app, but for the additional verification, a phone number was required until now. The messaging service is, therefore, now putting an end to this vulnerability by allowing the use of the verification app without specifying the telephone number.
