SMS has become a SHOULD-Have feature on every social network site for a variety of reasons. First, SMS verification can help protect user accounts from hackers by providing an extra layer of security. With an SMS verification system, users will be required to enter a security code sent to their mobile phone before accessing their account. This means that even if a hacker has access to the user's password, they won't be able to log into the account without the code. Second, SMS verification can help social network sites to protect user data by verifying the identity of users. By verifying users' identities, sites can ensure that user data is only accessible by the rightful owner. Finally, SMS verification can help social network sites to prevent spam and other malicious activity. By verifying users' identities, sites can more easily identify and block malicious users and bots.
