Why Privacy Myths Are Particularly Costly
Misconceptions about online privacy are not harmless. When people believe they are protected, they take fewer precautions — and that behavioral gap is exactly what attackers and data collectors rely on. The myths below are among the most widely held, and each one creates a specific, real vulnerability.
For readers who want a ground-level introduction to how personal data actually moves online, Online Privacy for People Who Don't Work in Tech provides useful context before diving in.
False Security Can Be More Dangerous Than No Security
Believing you are protected when you are not leads to riskier behavior online. Each myth below represents a real gap between perception and reality. Understanding these gaps is the first step toward making choices that actually protect your personal information.
The Myths, Corrected
Each of the following pairs a common belief with what the evidence actually shows — and explains the practical consequence of getting it wrong.
Myth
Incognito or private browsing mode makes you anonymous online.
Fact
Private browsing only prevents your device from storing your browsing history locally. Your internet service provider, employer networks, and the websites you visit can still see your activity.
Private browsing was designed for a narrow purpose: keeping your local browsing history off the device. It does not encrypt your traffic, mask your IP address, or stop websites from logging your visits. Your internet service provider (ISP) — the company that connects you to the internet — can still observe which sites you visit in private mode.
Websites also continue to identify you through techniques like browser fingerprinting, which builds a profile from your device's settings, screen resolution, installed fonts, and other characteristics — no cookie required.

Myth
I have nothing to hide, so privacy doesn't matter to me.
Fact
Privacy is not about hiding wrongdoing — it is about controlling who has access to your personal information and how it can be used against you.
This argument conflates privacy with secrecy about misconduct. In practice, personal data — including location history, health searches, financial behavior, and social connections — can be used in ways people never anticipated: in employment screening, insurance decisions, targeted manipulation, or identity theft.
Data brokers legally aggregate and sell this information, often without individuals knowing. Data Brokers: The Industry That Knows More About You Than You Realise details how extensive this profiling can become and what options exist to limit exposure. Privacy, in other words, is a structural protection — not a personal confession.
Myth
A strong, unique password is enough to keep an account secure.
Fact
Passwords alone are insufficient. Without two-factor authentication (2FA), a stolen or leaked password gives an attacker full account access.
Data breaches expose billions of credentials every year. Even a password that has never been reused can appear in a breach dump if the service storing it is compromised. Two-factor authentication adds a second verification step — typically a code sent to your phone or generated by an app — so that a password alone is not enough to log in.
How you store passwords also matters. Browser-saved passwords and dedicated password managers offer different levels of protection. Password Managers vs. Browser-Saved Passwords breaks down the practical differences in security between the two approaches.
Myth
Public Wi-Fi is perfectly safe as long as you use HTTPS websites.
Fact
HTTPS protects the content of your connection to a specific site but does not protect your device from other threats on a shared network.
HTTPS encrypts data between your browser and a website, which is a meaningful protection. However, on a public network, other risks remain: malicious hotspots can mimic legitimate networks, and attackers on the same network may attempt to exploit vulnerabilities in device software rather than intercept web traffic directly.
The actual risk landscape for public Wi-Fi is more nuanced than either "always dangerous" or "safe with HTTPS." Public Wi-Fi: What the Risks Actually Look Like examines what the evidence shows about specific threats in shared network environments.
Myth
Only large companies or celebrities get targeted by hackers — average people aren't worth the effort.
Fact
The majority of cyberattacks are automated and indiscriminate. Ordinary users are targeted constantly because volume, not notoriety, drives most attacks.
Credential stuffing, phishing, and malware campaigns are largely automated. Attackers run scripts that test stolen username and password combinations across thousands of services simultaneously. The goal is scale, not status. An ordinary account can be valuable for financial fraud, access to other accounts, or use in a botnet — a network of compromised devices used to carry out further attacks.
Phishing in particular has grown more convincing. Phishing Attacks: Why They Still Fool Smart People covers how modern social engineering techniques are designed to bypass skepticism, even among cautious users.
VPNs Do Not Make You Anonymous
A VPN encrypts your traffic and masks your IP address from websites you visit, but your VPN provider can still see your activity. If a provider keeps logs and receives a legal request, that data can be disclosed. Free VPNs in particular have a documented history of selling user data to third parties. Choose providers with independently audited no-log policies — and understand that no tool eliminates risk entirely.
Understanding where your data goes is part of the broader picture. Everyday social media habits and seemingly routine posts can also expose more than most people intend. Sharing Too Much: Where People Routinely Overshare Online Without Noticing looks at the specific ways routine sharing quietly accumulates into a detailed personal profile.
Privacy protection is built from layered, consistent habits — not single tools or one-time fixes. Digital Safety Habits That Hold Up Over Time outlines the foundational practices that security professionals consistently recommend for everyday users.
81%
Of breaches involve stolen or weak credentials
According to Verizon's Data Breach Investigations Report, the vast majority of hacking-related breaches exploit compromised passwords rather than sophisticated technical exploits.
~700M
Records exposed in data breaches annually
Industry tracking by organizations such as the Identity Theft Resource Center consistently documents hundreds of millions of records exposed each year across publicly reported breaches.
Billions
Consumer profiles held by data brokers
Estimates from privacy researchers and regulators suggest the data broker industry collectively holds detailed profiles on a significant proportion of the adult population in the United States.
