How to Enable 2FA Authentication

Two-factor authentication (2FA) is one of the most effective ways to protect your accounts. This guide will show you how to set it up.

What You'll Need

Before you start, prepare a smartphone with an authenticator app installed (we recommend Google Authenticator, Authy, or Microsoft Authenticator).

Step 1: Choose an Account to Secure

Start with your most important accounts. Priority list: Email account (most critical), Banking and financial accounts, Social media (Facebook, Twitter, Instagram), Work accounts and cloud storage.

Step 2: Find Security Settings

In each service, look for these names:

• Two-Factor Authentication (2FA)
• Two-Step Verification
• Security and Login
• Account Settings > Security

Step 3: Choose 2FA Method

If possible, choose 'Authenticator App' instead of SMS. SMS is vulnerable to SIM swapping, while apps are much more secure.

Step 4: Scan QR Code

The service will display a QR code. Open your authenticator app and scan it. The app will start generating 6-digit codes that change every 30 seconds.

Step 5: Save Backup Codes

Most services provide backup recovery codes. IMPORTANT: Save these codes in a secure location (password manager or physical vault). You'll need them if you lose your phone.

Step 6: Test It

Log out and log back in to test that 2FA works. Make sure you can get the code from your authenticator app.
