What Is Two-Factor Authentication?

**Two-factor authentication (2FA)** — also called two-step verification — adds a second layer of security to your online accounts. After entering your password, you are also asked to confirm your identity with a second piece of information that only you have access to.

Even if a hacker knows your password, they cannot log into your account without also passing the second factor.

Why It Matters

Passwords alone are not enough. They can be stolen through phishing emails, data breaches at websites you use, or guessed if they are weak. 2FA blocks the vast majority of account takeover attacks — including those where attackers already have your password.

The Types of Second Factors

  • **SMS code:** A one-time code sent to your phone via text message. Convenient but not the most secure option.
  • **Authenticator app:** An app like Google Authenticator or Microsoft Authenticator generates a time-based code every 30 seconds. More secure than SMS.
  • **Hardware key:** A physical USB device (like a YubiKey) that you insert or tap. The most secure option, used by high-security environments.

    • For most people, an **authenticator app** provides an excellent balance of security and convenience.

    How to Enable 2FA on Key Accounts

    Email (Gmail)

  • Go to your Google Account settings
  • Click **Security → 2-Step Verification**
  • Follow the prompts to set up an authenticator app or SMS backup

    • Email (Microsoft/Outlook)

  • Go to account.microsoft.com
  • Click **Security → Advanced security options**
  • Enable **Two-step verification**

    • Facebook

  • Go to **Settings and privacy → Settings → Security and login**
  • Click **Two-factor authentication** and follow the prompts

    • Banking

    Most Australian banks now offer or require 2FA. Check your bank's security settings in the app or online banking portal.

    Set Up a Backup Recovery Code

    When you enable 2FA, always save the backup recovery codes provided. These let you access your account if you ever lose your phone. Store them somewhere safe — not on the computer itself.
