What is MFA and why is it important
MFA stands for Multi-Factor Authentication. It is a security measure requiring users to present at least two different types of credentials before accessing an account or service. The goal is to reduce the risk of unauthorized access caused by stolen passwords or compromised devices.
How does MFA work
MFA authentication uses a combination of the following factors:
- Something you know: a password or PIN.
- Something you have: such as an OTP (One-Time Password) sent via SMS, a mobile app, or a hardware token.
- Something you are: biometric data, such as fingerprints or facial recognition.
For example, when logging into a web portal, you might first enter your username and password. Then, you receive an SMS with a one-time code you must enter to complete the login. This way, even if someone discovers your password, they cannot access your account without also accessing your phone.
