What is Multi-Factor Authentication (MFA)? Why do we need MFA?

Beyond Passwords: Understanding Multi-Factor Authentication (MFA)

In today's digital landscape, passwords alone are no longer enough to protect our sensitive information. Hackers are becoming increasingly sophisticated, employing tactics like phishing, malware, and brute-force attacks to gain access to our accounts.

That's where Multi-Factor Authentication (MFA) comes in, adding an extra layer of security to safeguard your online presence.  

What is MFA?

Multi-Factor Authentication (MFA) is a security system that requires more than one method of authentication to verify a user's identity before granting access to an account or application. Essentially, it's a way to prove you are who you say you are by presenting multiple forms of "credentials."   

Think of it like this: a password is like a key to your front door. MFA adds a deadbolt, a security camera, and maybe even a guard dog – making it significantly harder for intruders to get in.

How MFA Works:

When you enable MFA on an account, the login process changes. After entering your username and password (the "something you know" factor), you'll be prompted to provide an additional verification method. This could involve:   

• Entering a code generated by an authenticator app on your phone.   
• Approving a login request on your smartphone.
• Inserting a hardware security key into your computer's USB port.   
• Scanning your fingerprint.   

Only after successfully providing this second factor will you be granted access to your account.

Why is MFA Important?

• Enhanced Security: MFA significantly reduces the risk of unauthorized access, even if your password is compromised. 
• Protection Against Phishing: Even if you fall victim to a phishing scam and give away your password, the attacker will still need the second factor to gain access.
• Reduced Risk of Data Breaches: By making it harder for hackers to access accounts, MFA helps prevent data breaches and the loss of sensitive information.   
• Compliance Requirements: Many industries and regulations require MFA to protect sensitive data.  

Common Questions You Might Have:

• "Why do I need MFA?"
  • MFA is crucial for protecting sensitive company data and your personal information. It significantly reduces the risk of unauthorized access.
• "What if I lose my phone or can't access my authenticator app?"
  • This is why we provide backup recovery methods. If you lose access, contact the IT helpdesk immediately for assistance.
• "What if I don't have a smartphone?"
  • Please contact the IT helpdesk. We can discuss alternative MFA methods, such as SMS or a hardware token, if available.
• "How often will I need to use MFA?"
  • Typically, you'll be prompted for an MFA code each time you log in from a new device or location, or after a certain period of inactivity. Your company policy will dictate the exact frequency.
• "Is there a cost to use MFA?"
  • The authenticator apps are free. if your company uses hardware tokens, those will be provided to you.
