This refers to a method of verifying and granting access using a registered mobile telephone number within a system called NIA. The system sends a unique code to the registered number, which the user must then input to confirm their identity. As an example, accessing certain secure government services might require this verification step to ensure only authorized individuals can gain entry.
This security measure offers multiple advantages. It strengthens security by adding an extra layer of verification beyond a simple password. Its utility is enhanced by the ubiquity of mobile phone ownership, making it broadly accessible. Historically, such methods have evolved from simple password protection to multi-factor authentication schemes due to escalating cybersecurity threats and the need for more robust identity assurance.
