Getting Started with Online Privacy

You don’t need to be a cybersecurity expert or use complicated tools to protect your privacy online. The truth is that a few simple changes to your daily digital habits — and replacing a handful of services with privacy-respecting alternatives — will dramatically reduce how much of your data is collected, tracked, and sold.

This guide is for complete beginners. No technical jargon you’ll need a glossary for. No assumptions about what you already know. Just practical steps you can take today, starting with the ones that make the biggest difference.

Why Online Privacy Matters

Every website you visit, every search you make, every message you send — it all leaves a digital trail. Companies collect this data to build detailed profiles about you: your location, your habits, your health interests, your political leanings, who you talk to and when. These profiles are bought and sold by data brokers, used to target ads, and sometimes leaked in data breaches that expose your passwords and personal information.

Online privacy isn’t about hiding from the government or having something to hide. It’s about choosing who gets access to your personal information and for what purpose. It’s the digital equivalent of closing your curtains at night — not because you’re doing something wrong, but because your private life is yours.

Step 1: Use a Password Manager

This is the single most impactful change you can make. If you’re reusing passwords across different sites — or using simple passwords you can remember — you are one data breach away from losing access to your accounts. Data breaches happen constantly. When a site you use gets breached, your email and password end up in public databases that attackers use to try logging into your other accounts (banking, email, social media). This is called credential stuffing, and it works because most people reuse passwords.

A password manager solves this completely. It generates strong, unique passwords for every site and stores them in an encrypted vault. You only need to remember one master password.

Bitwarden is our top recommendation — it’s open source, free for all the features you need, and works on every platform. It has browser extensions for Chrome, Firefox, and Edge, mobile apps for iOS and Android, and a desktop app for Windows, Mac, and Linux. Your passwords sync securely across all your devices, and Bitwarden’s code is independently audited for security.

Set up Bitwarden today, install the browser extension, and let it generate a strong random password every time you create a new account. The browser extension will automatically fill your passwords when you log in. After a week of using it, you’ll wonder how you ever managed without it.

Step 2: Switch to Encrypted Messaging

Standard SMS text messages and most messaging apps (including Facebook Messenger and Telegram by default) are not end-to-end encrypted. This means the company that runs the service can read your messages — and so can anyone who intercepts them or gains access to the company’s servers.

Signal fixes this. Every message, every call, every photo you send on Signal is end-to-end encrypted by default. Not even Signal’s operators can read your conversations. It’s free, open source, and runs on iPhone and Android. The desktop app lets you continue conversations from your computer.

Signal uses your existing phone number for registration, which makes it easy to find friends who are already using it. Once you’re both on Signal, all your communication is private — no data collection, no ad profiling, no message scanning. Signal’s encryption protocol is so respected that WhatsApp and Google Messages both use it for their own encrypted chats.

Getting your friends and family to switch is the hardest part. Start by installing Signal yourself, then send a message to your most tech-savvy contacts: “I’m moving our chat to Signal for privacy. Here’s a link to install it.” Once a few people make the switch, others will follow.

Step 3: Use a VPN

A VPN (Virtual Private Network) encrypts all the internet traffic between your device and the VPN server. This means your internet service provider (ISP) cannot see which websites you visit, and websites cannot see your real IP address or physical location. A VPN is essential when using public Wi-Fi (coffee shops, airports, hotels), where attackers can easily intercept unencrypted traffic.

Not all VPNs are created equal. Many free VPNs actually collect and sell your data — defeating the entire purpose. Stick with trusted, open-source or audited providers that have a proven no-logs policy:

• Proton VPN — Swiss-based, open source, strong privacy laws, has a free tier (data-limited but privacy-respecting). Created by the same team behind Proton Mail.
• WireGuard — Modern, fast, and audited VPN protocol. Many VPN providers use it as their underlying technology. It’s built into the Linux kernel and available on all platforms.
• OpenVPN — The tried-and-true open-source VPN protocol. Slower than WireGuard but battle-tested over decades of use.

For most people, Proton VPN’s free tier is an excellent starting point. Install the app, connect with one click, and your internet traffic is encrypted from that moment on.

Step 4: Lock Down Your Browser

Your web browser is the window through which most of your data leaks — trackers, cookies, fingerprinting scripts, and ads all enter through your browser. A few simple changes make a huge difference.

Switch to Mozilla Firefox or Tor Browser. Firefox is a privacy-respecting mainstream browser with strong tracking protection built in. Enable its “Strict” privacy mode in Settings → Privacy & Security, and most trackers will be blocked automatically. Tor Browser routes your traffic through multiple relays for maximum anonymity — it’s slower but ideal for sensitive browsing.

Install these essential privacy extensions:

• uBlock Origin — Blocks ads, trackers, and malware domains. It’s lightweight, open source, and blocks more than any other ad blocker. Every browser should have this installed.
• Privacy Badger — Created by the Electronic Frontier Foundation (EFF), this extension learns to block invisible trackers that follow you across websites.

Together, these changes will eliminate most tracking scripts, block nearly all ads, and prevent websites from fingerprinting your browser configuration.

Step 5: Encrypt Your Files

Encryption ensures that even if someone gains physical access to your computer, phone, or external drive, they cannot read your files without the encryption key.

• VeraCrypt — Creates encrypted volumes or entire disk encryption. Perfect for encrypting external drives or creating a secure folder for sensitive documents. It’s the successor to TrueCrypt and has been thoroughly audited.
• Cryptomator — Encrypts individual files before they sync to cloud services like Dropbox, Google Drive, or Nextcloud. This means your cloud provider cannot read your files even if they wanted to. Works on Windows, Mac, Linux, iOS, and Android.
• Aegis Authenticator — Enables two-factor authentication (2FA) for your online accounts, adding a second layer of security beyond your password. It’s open source, free, and supports encrypted backups.

Putting It All Together

You don’t need to do everything at once. Here’s a suggested order of operations, starting with the highest-impact changes:

The Bottom Line

You don’t need to overhaul your entire digital life overnight. Start with a password manager — that’s the single most important step. Add encrypted messaging and a VPN next. Then lock down your browser. Each step builds on the last, and each one makes you significantly more private than you were before.
