Multi-Factor Authentication

A popular use case example of MFA is receiving a one-time passcode and entering it along with your username and password. This is a two-line defense, as users need to enter their credentials or something they know and then add the code that’s often sent to their smartphone device via SMS. Only if both steps are completed successfully can the user access the app or website. 

Multi-factor authentication can be set up in various ways, depending on the business and its chosen user flow. 

Here’s a step-by-step explanation of the process:

1. The user is asked to enter a passcode into a third-party app, which is designed to verify their identity.
2. The user is asked to provide biometric data, like recording a short video of their face, for authentication.

For example, the system can ask the user to complete MFA only on a new device and ask for their password on recognized devices.

The most common forms of MFA include:

1. Knowledge-based authentication (KBA), which is verifying a user’s identity by asking them security questions or “secrets” that only they would be able to answer. 
2. Token-based authentication, which is based on an email, software, phone, or SMS token, allows the user to access a web or an app without repeatedly entering their credentials.
3. Biometric authentication, which uses the person’s unique biometric features, like their face, asking them to upload a selfie picture or a video as a way to verify their identity, ensure they’re a real person, and that they aren’t using stolen information.

Multi-factor authentication helps businesses enable remote access to their networks, which is vital in today’s digital era. It benefits organizations by protecting their data and securing user transactions or interactions. The biggest benefit from the user’s side is that it’s a simple, fast, and secure way to log in to a system without chances of human error. Multi-factor authentication solutions can also send alerts for suspicious login attempts, which protects from unauthorized access. 

Multi-factor authentication methods that rely on inheritance mean that the user will need to use their unique traits to authenticate themselves. 

For example, this could be:

• Retina scans
• Facial recognition
• Fingerprint scans
• Voice recognition
