How can two factor authentications protect sensitive information?
By using an additional layer of security (a second factor), customers can be protected from fraudulent attempts to access their online accounts. When customers trying to log-in to an account need to provide further proof of ID in addition to a password, things can get a bit more difficult for people trying to access accounts unlawfully. Someone may have figured out your password, but do they have the mobile phone that the PIN number will be texted to, or the ID card to swipe and complete the second factor required to gain access?
That’s how 2FA (two factor authentication) can protect sensitive information – you need to have both factors to get access, knowing or having one is not enough.
