You wouldn’t drive without a seat belt. You wouldn’t leave your office unlocked overnight. So why go online without multi-factor authentication (MFA)?
MFA is like a second lock on your digital door. Instead of relying on just a password—which can be stolen, guessed, or phished—it adds another layer of protection, such as a text code, authentication app, or fingerprint scan. Even if a hacker gets your password, without that second step they’ll hit a dead end.
How MFA Protects You
If locking your front door at night is your password, arming your security system before heading to bed is MFA. Sure, it isn’t strictly necessary—but isn’t it nice to know that you’re still safe if one protection fails?
That’s exactly what MFA does. It simply adds a quick extra step to confirm that it really is you logging in.
There are several terms for MFA, such as “two-step verification,” “two-factor authentication,” or a “one-time password,” but it all means the same thing—two or more steps to confirm your identity before granting access to confidential information.
Common forms of MFA include:
- Account-creation confirmation emails.
- Bank security questions.
- Text codes.
- Push notifications.
- Phone calls.
- Biometric scans (fingerprint, face ID)
Real-Life Moments When MFA Saves the Day
While MFA is quick and easy for you—just click a button or enter a code—it’s a major roadblock for hackers. If an unauthorized user tries to log in to your account, MFA will send you a notification or code, alerting you to the breach. This gives you a chance to change your password before hacker steal your data.
MFA also stops anyone trying to use a stolen password from accessing your systems. Even if a hacker tricks an employee into sharing their login, they still won’t get in without that extra step.
Case Study: A small business recently avoided a costly data breach when an attacker got an employee’s password through phishing. Because they had MFA set up, the attacker could not access the account, and the system immediately alerted the employee to change their credentials.
How to Set Up MFA: Step-by-Step
The most important places to enable MFA are:
- Banking and finance apps.
- Email and cloud storage.
- Social media accounts.
- Work logins with client or proprietary information.
How to Enable MFA on Google:
- Go to your Google Account Security settings.
- Click “2-Step Verification.”
- Follow the prompts to add your phone or authenticator app.
How to Enable MFA on Microsoft:
- Sign in to your Microsoft account.
- Go to Security > Advanced security options.
- Select “Turn on” under Two-step verification and follow the instructions.
MFA Myths & Misconceptions
MFA is too complicated.
Most MFA methods are as simple as tapping a button or entering a short code.
MFA slows me down.
The extra step takes only a few seconds and can save you from weeks (or years) of damage control.
I don’t need MFA for personal accounts.
Hackers often target personal accounts to gain access to work or financial information.
Best Practices for MFA
- Use an authenticator app instead of SMS when possible (apps are less vulnerable to SIM-swapping attacks).
- Regularly update your recovery options and backup codes.
- Educate your team about phishing and social engineering tactics.

Most services offer backup codes or alternative verification methods. Set these up in advance to avoid being locked out.
Is MFA necessary for every account?
At minimum, enable MFA on accounts with sensitive or financial information. The more accounts protected, the safer you are.
Is it possible for someone to hack MFA?
While no security is perfect, MFA makes it exponentially harder for attackers to access your accounts.
