Take the time to lock the door

In the ever-evolving realm of technology, we find ourselves at the intersection of convenience and security. EDIN READ takes a closer look at a crucial aspect of online security that might initially seem a mystery – two-factor authentication (2FA).

Picture this: You’re about to log into one of your online accounts and suddenly, a request for a code arrives on your phone or email. Questions naturally arise. Why this extra step, and how does it contribute to my security?

These are common queries, and I’m here to demystify the process and underline why 2FA stands as one of the most effective and user-friendly security measures available.

Two-factor authentication is essentially your digital bouncer, poised to safeguard your accounts from unauthorised access.

It introduces an additional layer of protection beyond the traditional username and password combination.

Here’s how it works: when you log in, you provide your standard credentials (username and password). Then, like a personalized key, an additional unique code is sent to your device. This code is not a static password; it’s a dynamic, time-sensitive passphrase, only valid for a brief period.

You then take this one-time code and type it in to where you were logging in and continue as normal. There’s no need to record this password like you normally would as it is only for that time you’re logging in. Next time you log in, a new one will be sent to you.

Think of it as a secret handshake that changes every time.

This dynamic element makes it significantly more challenging for cyber adversaries or automated systems to compromise your accounts.

Even if your password was somehow compromised, this extra hurdle adds an invaluable layer of defence as you’ll get an alert every time someone goes to log in (or you,  good sign that it’s working).

Now, you might be wondering where you can implement 2FA. Many companies recognise the strength of 2FA, so it’s available almost everywhere.

Major online platforms, from email services to social media and banking, offer 2FA options.

Sometimes, you won’t have the choice to enable it as the company has already decided that to have an account with them, 2FA is a must.

Not all logins have the option either – for example, your main computer password to log in won’t have the option, and this is OK.

Your Apple ID (if you have one) has used 2FA for years and you might not have even realised.

When you go to reset your password for them after you’ve forgotten it (yes, this happens to me all too often!), a code will be sent to another one of your devices.

You enter this code on to the first device and continue to change your password as normal. This is a way of Apple verifying that it’s you wanting to sign in and not a robot on the other side of the world trying to crack into your account.

Consider this as the digital equivalent of locking your front door. Sure, it might take a moment longer, but it significantly enhances your security and peace of mind.

This extra layer is particularly crucial in today’s landscape of sophisticated cyber threats and data breaches.

While two-factor authentication may introduce a minor adjustment to your online routine, the transparency of its process and the enhanced security it provides make it an invaluable ally in your digital journey.

As we continue to explore the wonders of technology, let’s ensure our digital experiences are not only enjoyable but also fortified against potential threats.

The next time you encounter that prompt for an extra code, embrace it as your personalized security detail, ensuring your online experiences remain safe, secure, and truly yours.
