Account holders are required to use two authentication methods in addition to their passwords as part of two-factor authentication, which is designed to increase account security. Twitter supports 2FA through SMS, an authentication app, and a security key.
The company believes “bad actors” are misusing phone-number-based 2FA, according to a blog post from Wednesday to which the company’s tweet contained a link.
