What is Two-Factor Authentication (2FA)?

<p>The days of saying "my password is complex, nothing will happen to me" are unfortunately over. <strong>Two-Factor Authentication</strong> (or <strong>2FA</strong>) is a method of protecting your account with a second layer of security, rather than just a password.</p> <p>Think of it like your home security: If your password is the lock on the door, 2FA is the deadbolt inside. Even if someone steals your key, they cannot get in as long as the deadbolt is locked.</p> <h3>How Does It Work? (The Logic is Simple)</h3> <p>In a standard login, you only use <strong>something you know</strong> (your password). When 2FA is active, the system requires you to prove <strong>something you have</strong> as well.</p> <p>The process works like this: 1. <strong>Step:</strong> You enter your username and password. 2. <strong>Step:</strong> You enter a 6-digit code sent to your phone or generated by an app, which is usually valid for a short time (typically 30 seconds). 3. <strong>Result:</strong> The system confirms you are really "you" and opens the doors.</p> <h3>Why Should You Use Two-Factor Authentication?</h3> <ul> <li><strong>Shield Against Password Leaks:</strong> Even if a website you use gets hacked and your password is leaked, attackers cannot access your account because they don't have the constantly changing code on your phone.</li> <li><strong>Phishing Protection:</strong> Even if you accidentally enter your password on a fake website, your account remains secure without the second factor.</li> </ul> <h3>2FA Methods: Which is Better?</h3> <p>There are several different methods for two-factor authentication. Here is a quick comparison in terms of security and ease of use:</p> <table> <thead> <tr> <th>Method</th> <th>How it Works?</th> <th>Security Level</th> </tr> </thead> <tbody> <tr> <td><strong>SMS</strong></td> <td>A code is sent to your phone via text.</td> <td>Medium</td> </tr> <tr> <td><strong>Email</strong></td> <td>A code is sent to your email address.</td> <td>Medium</td> </tr> <tr> <td><strong>Authenticator Apps</strong></td> <td>Generates a new code every 30 seconds.</td> <td><strong>High</strong></td> </tr> </tbody> </table> <h3>The Most Practical Way to Manage Your Codes: Koda</h3> <p>When you enable 2FA for dozens of different accounts (Banking, Social Media, Email, GitHub, etc.), managing these codes can get a bit complicated.
