Two-Factor Authentication (2FA) is a security process that requires two forms of identification before granting access to an account or system. It adds an extra layer of protection by combining something you know (a password) with something you have (a second factor, such as a phone or authentication app).

How 2FA Works:

1. Step 1: Enter your username and password.
2. Step 2: After the password is correct, the system will prompt you to enter a second factor, such as:
   • A code sent via SMS.
   • A code generated by an authenticator app (e.g., Google Authenticator, Authy).
   • A physical security key (USB device or Bluetooth).

Why Is 2FA Important?

• Enhanced Security: Even if someone steals your password, they won’t be able to access your account without the second factor.
• Protection Against Hacks: 2FA helps guard against common threats like phishing, keylogging, and brute force attacks.
• Safe Crypto Storage: For crypto wallets or exchanges, enabling 2FA makes it much harder for hackers to access your funds, adding significant security to your assets.
• Account Integrity: Ensures that only you can access your sensitive accounts, protecting personal data, email, and financial information.

Best Practices for 2FA:

• Use Authenticator Apps: These are more secure than SMS-based 2FA, as SIM swaps and network vulnerabilities can compromise SMS codes.
• Enable 2FA Everywhere: Activate 2FA for all critical accounts, including email, crypto exchanges, and social media, to provide better security across the board.
