How to Set Up Two-Factor Authentication (2FA) on Every App That Matters

How to Set Up Two-Factor Authentication (2FA) on Every App That Matters

By David V. | 3/4/2026

What Is 2FA, Really?

 

2FA (a type of MFA) adds a second step to your login, so even if someone has your password, they still can’t get in without another factor.

 

You log in with:

 

  • Something you know (your password)

  • Plus something you have (a code/app prompt/security key)

 

Google’s research found that adding a second step can stop 100% of automated bots and the majority of bulk phishing attempts (depending on the method).¹ CISA also says enabling MFA makes you 99% less likely to get hacked.²

Best Practice (Quick + Strong)

 

Prefer an authenticator app or device prompt over SMS text codes when you have the option. Device prompts and app-based methods generally hold up better against common attacks than SMS.¹

 

Common authenticator apps:

 

  • Google Authenticator

  • Microsoft Authenticator

 

(If you use Authy, note that Twilio ended support for the Authy Desktop app in 2024—mobile still works, but don’t rely on desktop going forward.³)
