Why You Should Use Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) adds an extra layer of security to your online accounts. Even if attackers steal your password, they cannot log in without the second factor—such as a code sent to your phone or generated by an authenticator app.

What is 2FA?

2FA requires you to provide two forms of verification before gaining access:

• Something you know — Your password.
• Something you have — A phone, hardware key, or authenticator app.
• Something you are — (Optional) Biometric verification like a fingerprint or face scan.

Why It Matters

• Prevents account takeovers even if your password is leaked in a data breach.
• Protects sensitive information like emails, banking, and work accounts.
• Makes phishing attacks less effective since attackers need more than just your password.
• Required by many organizations for compliance and security standards.

Common Types of 2FA

• SMS Codes — A one-time code sent via text message.
• Authenticator Apps (Google Authenticator, Authy, Microsoft Authenticator).
• Push Notifications — Approve login attempts via your mobile app.
• Hardware Tokens — Devices like YubiKey or RSA key fobs.
• Biometrics — Fingerprint, Face ID, or voice recognition.

Best Practices

• Enable 2FA on all critical accounts: email, banking, social media, and work systems.
• Prefer authenticator apps or hardware tokens over SMS for stronger protection.
• Store backup recovery codes in a safe location.
• Regularly review and update your 2FA settings.

Bottom line: 2FA makes it much harder for attackers to break into your accounts. It’s one of the simplest and most effective ways to protect your digital life.
