A disposable or short-term telephone number can be used to satisfy the security requirements of social media platforms, like those needed when creating an account or enabling two-factor authentication. These numbers are not linked to a user’s personal information and often expire after a short period. They function by receiving SMS messages containing verification codes sent by the platform, allowing the user to confirm their identity without providing their primary contact details.
Employing this method offers a degree of privacy and can limit exposure to potential spam or unwanted solicitations. Historically, the use of such services arose due to growing concerns about data privacy and the desire to control the personal information shared online. It represents a balance between security protocols demanded by online platforms and the individual’s right to protect their personal contact details.
