SMS Authentication

SMS authentication is a security process that uses text messages to verify a user's identity. When you log into an account, the system sends a unique code to your mobile phone via SMS. You then enter this code on the website or app to prove you are the rightful owner of the account. This two-step verification adds an extra layer of security beyond just a password, making it harder for unauthorized users to gain access. It’s commonly used for banking, social media, and online services to protect personal information.
