What is two-factor authentication? The extra security layer you need to know about

Today, we’re diving into a subject that’s crucial for everyone in the digital age: what is two-factor authentication, or as it’s more commonly referred to, 2FA.

What is two-factor authentication (2FA)?

Let’s simplify this. Imagine your phone as your personal sanctuary, like your home. Usually, you’d unlock the door with a key, right? Well, two-factor authentication takes it a step further by requiring an additional, unique code that only you would have access to. Essentially, 2FA acts as a second layer of security for your online accounts. It serves as a digital double-check to make sure you are the only person accessing your important information.

The importance of 2FA: Why should you care?

Remembering passwords is often seen as troublesome. So, why add another security step? The answer lies in its ability to provide robust protection. If someone were to crack your password—which happens more frequently than you’d think—they would still need to pass through the second layer of authentication, making 2FA invaluable for keeping your personal information secure.

How to enable two-factor authentication: A beginner’s guide

Excited to jump on the 2FA bandwagon? Here’s how to enable two-factor authentication on various platforms:

Google Account:

  1. Log in: First, access your Google Account settings.
  2. Security tab: Look for the “Security” tab on the navigation menu.
  3. 2-Step verification: Scroll until you find “2-Step Verification” and follow the guidelines. Typically, you’ll either add a phone number for receiving SMS codes or use an Authenticator app.


  1. Settings: Navigate to your account settings.
  2. Security and login: Click on this tab.
  3. Two-factor authentication: This option will appear under the security settings. Follow the procedure, similar to that of Google, to activate 2FA.

Apple ID:

  1. Apple ID settings: Access your Apple ID account online.
  2. Security section: Locate this tab.
  3. Two-factor authentication: You’ll find an option to enable 2FA, usually through a trusted phone number or device. Follow the directions accordingly.

Your first steps towards enhanced online security

There you have it! With just a few steps, you can significantly strengthen the security of your online accounts. While enabling two-factor authentication may seem like a small tweak, it has a huge impact on the safeguarding of your digital assets and personal information.
