Two-Factor Authentication (2FA) is an added layer of security used to protect your online accounts. It requires two forms of verification before granting access to your account, making it harder for unauthorized individuals to gain access.
The Two Factors:
• Something You Know: This is usually your password or PIN.
• Something You Have: This could be a code sent to your phone (via SMS, email, or an app like Google Authenticator) or a physical security key (e.g., a USB device).
How It Works:
• Step 1: You enter your password (the first factor).
• Step 2: You are then asked for a second form of verification, like a one-time code sent to your phone or generated by an authenticator app.
Even if a hacker knows your password, they would still need access to your second factor (e.g., your phone or authentication app) to gain entry, making it much more secure than just a password alone.
Why It’s Important:
2FA adds an extra layer of security, making it harder for cybercriminals to access your sensitive information. It significantly reduces the chances of account hacking, even if your password is compromised.
