Security

Beginner
## What Is 2FA? | Two-Factor Authentication
What Is 2FA? 2FA (Two-Factor Authentication) a security process that requires users to provide two different authentication factors to verify their identity. This typically combines something you know (password) with something you have (phone) or something you are (fingerprint).

## Why This Matters for Your Business
2FA blocks over 99% of automated account attacks according to Microsoft. If your business uses email, cloud storage, or any SaaS platform, enabling 2FA is the single most impactful security step you can take — often at zero cost.
