Two Factor Authentication: Protecting Your Business, Employees, and Customers via SMS

What does Two Factor Authentication mean?

Two-factor authentication or multiple-step verification is a process to check user’s identity twice for determining their legitimacy. Mostly, the account holder will be asked for two separate passwords to access his account. The first password will be his primary password and second is an authentication code or known as one-time password (OPT) which will be different for each login. OPT is entered into an application or website within a certain period of time to access the account. This adds an extra layer of security to the user’s account login by requiring two forms of authentication.


Use of SMS for Two Factor Authentication                 

Many online businesses are using two-factor authentication as a security tool to log in any application. For instance, the two-step verification required for signing into a Google account. If you have activated this feature, every time you sign in to your Google account, you need to enter your primary password and OPT generated from text message or voice call.
