Standard Multi-Factor Authentication Methods To Adopt

FREMONT, CA: Over the past decade, multi-factor authentication (MFA) has become a symbol of the mobile device business. One must have interacted with an MFA-enabled system if they have ever had to enter an authentication code, receive an SMS, or scan some hardware. MFA is extensively used, but it is far from flawless—whether one owns a corporation or is a user. Here are the five most prevalent MFA methods.

Hardware OTP (one-time-password) Tokens

One-time codes are created by hardware-based devices using a cryptographic key stored in the device. A server contains the same cryptographic key and can produce the same OTP to check that the value provided by the user is valid. A physical token that displays a OTP on a built-in screen, or a tool with a keypad that needs a user to input a PIN code before displaying a one-time password, are examples of user interfaces (UIs).

Soft token Software Development Kits (SDKs)

This software employs cryptographic processes to authenticate the user and device and can be embedded into mobile apps. There is no need to hop between apps or rely on a hardware device with these solutions; the UX is usually smoother. Soft-token SDKs offer advanced cryptography, such as digital signatures, which provides considerable security benefits.

SMS-based OTPs

This is a simple solution that does not require consumers to download any software. To authenticate, an OTP is delivered to the user's registered phone through SMS, which is used to authenticate them.

Cryptographic Hardware Tokens and Smartcards

Physical devices that can execute cryptographic operations such as decryption and signing while keeping the keys safe inside a fully isolated secure enclave. They can be used to log in to PCs (through Windows Smartcard Logon, for instance) and digitally sign transactions to ensure that the authentic user authorized the transaction. Smartcards can be contactless or require a specialized reader; cryptographic hardware tokens are commonly connected through USB.
