SMS-based two-factor authentication (2FA) remains a widely used and secure method for protecting online accounts, providing an extra layer of security beyond just a username and password. When you log in, you enter your usual credentials, but you’re also asked to provide a one-time password (OTP) or secret code sent directly to your phone via text message.
This makes it significantly harder for unauthorised users to access your account, as they would need both your login details and physical access to your phone.
For most users, SMS 2FA is a simple, convenient, and secure way to protect sensitive data from unauthorised access. It’s an accessible solution that remains a valuable defence against account hijacking.
