The Updated Guide to Online Privacy and Security

Right after food, water, and air, I (personally) think the internet is one of the best things to happen to man. There are about 7.7 billion people on earth and according to, over 4 billion people use the internet in 2019. That’s more than half of the world’s population.

The internet is a beautiful place; a medium to obtain & exchange information, work, have fun, make money, communicate, meet people, learn stuff, and do a whole lot more. However, despite the good that the internet has to offer, things can get really ugly as well.

In so many different ways, people have been scammed on the internet, their monies (and identities) have been stolen, accounts have been compromised and so on. And these things are avoidable. Carefully go through this guide to have a full understanding of how you can stay protected on the internet — on mobile & mobile apps, PC & desktop software, etc.

A. General Security and Authentication

i. Protect yourself from other individuals

Before now, a good number of internet users accessed the web via laptops and desktops. Things are quite different now as smartphones and mobile apps have disrupted PC. And since, unlike PC, smartphones can get stolen or misplaced easily, the very first step of securing your online accounts is creating strong passwords, PINs, and patterns. Biometric authentication methods like fingerprint, Face ID, Iris scanning, and Palm Unlock are also other secure ways of protecting your smartphone and mobile app.

There are times when you aren’t sure if your account passwords have been compromised or not. There are certain tools (like Google Chrome’s Password Leak Detection) that help you figure out which of your passwords have been compromised in data breaches.

The list below contains links to useful information, tutorials, and guides that’ll help you strengthen your mobile and app security. And ultimately, protect you from any harm on the internet.

ii. Creating Strong Passwords

Online security and privacy

Anything worth doing is worth doing well, they say. The same applies to creating passwords to safeguard your accounts on the internet. You shouldn’t just create passwords for the sake of it. Your password should be “strong”. It should contain a balanced mix of certain elements and ultimately, be very difficult to hack, guessed, or bypass. And yes, there are some passwords you should NEVER use to secure your accounts. Check them out.

iii. Two-Factor Authentication — Passwords aren’t enough

Sometimes, it’s not even enough having a strong password; you should further beef up your mobile account’s security via 2-Factor Authentication (also called 2FA or 2-Step Verification). Enabling 2FA in your online accounts will require you input some sort of code (in addition to your password) which would be sent to your phone number as a text, to a physical token, or the authenticator app on your smartphone.

We have put together a comprehensive guide on everything you need to know about 2-Factor Authentication — when, why and how to use it to secure your account online.

Hackers, spoofers, and individuals aren’t the only ones that constantly lurk on the internet to steal your data. Corporations do it too. Sometimes, your internet service provider (ISP) harvests personal data about your activities on the web and sells to third-parties —who in turn use such info for advertising targeting— without your consent. Not all ISPs do this but the truth is, there’s really no way for you to find out if they do… or not.

iii. HTTPS & SSL certificates

When you surf the web in your browser, some websites URL start with http:// and some, https://. The additional “S” has a meaning to it and you should ensure that whatever website you’re surfing on the world wide web has a https:// at the beginning of the URL.


The extra S stands for Secure Sockets Layer (SSL) and is an indication that your connection with the website is private and whatever information you provide on the site cannot be intercepted by a third-party who may want to use it for fraudulent activities. Whenever you’re surfing a website that doesn’t have the SSL certificate, some browsers (especially Chrome) will alert you that the website isn’t secure. Whenever you this warning, make sure you do not provide sensitive information on the website.

not secure

SSL (Secure Sockets Layer) is the standard technology for keeping an internet connection secure and safeguarding any sensitive data that is being sent between two systems (like a website and a server) so as to prevent criminals from reading and modifying any information transferred, including potential personal details, credit card details, bank login credentials, passwords, etc.

iv. Privacy-focused Browsers & Search Engines

Not sure if you know this but the moment you log onto the internet, you leave a trace that tells a lot about you to certain people and corporations. Your browser, for example, knows more than you think. Asides the fact that it (your browser) takes note of your browsing history, other data like location information, operating system details, plugins installed, time zone the computer is set to, language, screen size and other information are garnered through a process known as “fingerprinting”.

Some browsers are also not generally secure and allow hackers and third-parties access your data so easily. That’s why should consider using privacy-focused browsers. These privacy-focused web browsers limit ads, incessant spam, monitoring, and tracking to the barest minimum.

About search engines, they also collect and harvest a lot of your personal information. That’s the (hidden) price you pay for using their services for free. The solution to keeping your private information private when searching for information online is to use privacy-focused search engines — DuckDuckGo is a good example.

iii. Geo-tagging

Despite the fact that the average internet user is now more privacy-conscious about the type of information shared online, we still subconsciously give out certain (sensitive) data without even realizing it.

Geo-tagging is the process of attaching location information to media files like photos and videos. When a media file is “geo-tagged”, it basically means that the device (digital camera, smartphone, tablet, etc.) that captured the file has embedded GPS coordinates in the file metadata.

Although geo-tagging a photo has some useful applications like helping you organize pictures in your gallery based on location, it also comes with its associated (privacy) risks too. A stranger can download your pictures on the internet, extract GPS coordinates and track you.
