If your password gets stolen, MFA can stop attackers from logging in. It’s one of the simplest and most powerful security upgrades you can enable.
What Is MFA?
MFA requires two or more of:
- Something you know (password)
- Something you have (phone/app)
- Something you are (biometrics)
Why Passwords Alone Aren’t Enough
Passwords can be:
- Phished
- Leaked in data breaches
- Guessed or brute-forced
MFA blocks access even if your password is exposed.
Best Types of MFA
- Authenticator apps
- Hardware security keys
- Biometric verification
Avoid SMS when possible.
Quick Summary
- Turn on MFA everywhere
- Use authenticator apps over SMS
- Never approve login prompts you didn’t initiate
- Protect your email account first
