Two-Factor Authentication: Improved Account Security With SMS

A password just isn't good enough anymore. Protect your customers' data wherever they are, using only their mobile phone!

What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is an added layer of security. When your users try to access their account, you need to verify who they say they are, besides just using their username and password – like a One-Time Password (OTP).

Instead of immediately gaining access, you will be required to provide another piece of information (second factor of authentication) which could come in the form of something:

  • You know

    It could be a PIN (personal identification number), a one-time password (OTP), answers to “secret questions” or a specific keystroke pattern

  • You have

    Something in their possession, like a credit card, a smartphone, or a token

  • You are

    A bit more advanced category like biometric pattern of a fingerprint, an iris scan, or a voice print

Why SMS-based authentication?

  • No additional hardware needed

    The only thing your customers need is their mobile phone.

  • Works on any mobile phone

    No need for any kind of app – if your users don’t have a smartphone, this may be the only reliable authentication option.

  • Global

    Your users can be verified anywhere in the world – no mobile data required.

How to use one-time passwords (OTPs)

  • When a new user registers for your application, phone verification can help authenticate identity, ensuring your new user is who they claim to be – linking a user and their device.

    • User downloads an app and registers a new account

    • User receives a PIN code via a messaging service such as SMS or via a voice message 

    • User enters the PIN in the app on their device to complete the user registration process
