Multi-Factor Authentication (MFA)

MFA (Multi-Factor Authentication) is a login security method that requires two or more ways to verify your identity — like a password and a fingerprint — to prevent unauthorized access.

Definition

Multi-Factor Authentication (MFA) strengthens account security by requiring users to confirm their identity using multiple types of authentication. These typically include:

Something you know — like a password or PIN
Something you have — like a phone, token, or authentication app
Something you are — like biometric data such as a fingerprint or facial scan

This layered approach makes it significantly harder for attackers to gain access, even if one method is compromised.

Why It Matters

Passwords alone are no longer enough. With rising cybersecurity threats and phishing attacks, MFA adds a critical line of defense. It’s now a best practice in high-risk industries such as digital banking, e-commerce, and SaaS platforms.

Real-World Example

When logging into your business dashboard:

You enter your password
You receive a code on your mobile app
You scan your fingerprint to confirm

All steps must succeed to grant access — protecting both data and identity.

At Crebos

We recommend and implement MFA across all custom automation tools, admin dashboards, and internal systems — especially those handling sensitive or financial data. It’s one of the simplest, most effective steps toward better security and business resilience.
