How to Protect Your Online Privacy in 2026

Start with the privacy basics

Every search, login, app permission, location ping and newsletter sign-up can add to your digital footprint. Advertisers, platforms, data brokers and criminals all value that information for different reasons. The aim is not to make yourself impossible to trace. For most people, the aim is to make everyday tracking, profiling and account takeover much harder.

A strong online privacy setup has four layers: your connection, your accounts, your browser and your exposed personal data. If one layer fails, the others still reduce the damage.

Use a VPN, but understand what it can and cannot do

A VPN encrypts traffic between your device and the VPN server. This can help stop your internet service provider, a public Wi-Fi operator or someone on the same local network from easily seeing the sites and services you connect to. It is especially useful on hotel, airport, café and shared Wi-Fi networks.

A VPN does not make you invisible. Your VPN provider can see connection information, websites can still recognise you when you log in, and trackers can still use cookies, device signals and browser fingerprinting. Treat a VPN as one privacy layer, not a complete identity shield.

• Choose a provider carefully: look for a clear no-logs policy, independent audits, transparent ownership, modern protocols and sensible security features such as a kill switch and DNS leak protection.
• Keep HTTPS enabled: HTTPS protects the contents of the connection between your browser and the website. A VPN is not a replacement for secure websites.
• Use encrypted DNS where appropriate: encrypted DNS can reduce plain-text DNS exposure, but it does not hide everything you do online.
• Be cautious with free VPNs: a free VPN still has to be funded. Some free services rely on adverts, limited data, upselling or data collection, so check the trade-offs before trusting one with your browsing.

Protect your accounts with passkeys, MFA and a password manager

Your email account, password manager, cloud storage and banking apps deserve the strongest protection. If an attacker gets into your main inbox, they can often reset passwords for many other services.

• Use passkeys where available: passkeys are easier to use than complex passwords and much harder to phish because they are tied to the genuine website or app.
• Turn on multi-factor authentication: use MFA for your email, password manager, bank, cloud storage, social media and shopping accounts.
• Prefer stronger MFA over SMS: authenticator apps, device prompts, passkeys and hardware security keys are usually better than text-message codes.
• Use a password manager: for accounts that do not yet support passkeys, use long, unique passwords generated and stored by a reputable password manager.
• Secure account recovery: review recovery email addresses, phone numbers and backup codes. Weak recovery settings can bypass otherwise strong security.

Reduce browser tracking and fingerprinting

Your browser can reveal more than you might expect. Cookies are only part of the issue. Websites and ad-tech systems can also use your screen size, installed fonts, extensions, language settings, device details and behaviour to build a browser fingerprint.

The practical answer is not to install every privacy extension you can find. Too many unusual extensions can make your browser more distinctive and can slow pages down. Keep your browser setup simple, current and consistent.

• Separate browsing by purpose: use one browser profile for signed-in accounts and another for general browsing, research and reading.
• Stay signed out when possible: if you are logged into major platforms while browsing, more activity can be linked back to you.
• Block trackers sensibly: use built-in tracking protection and a reputable content blocker, but avoid turning your browser into a fragile collection of overlapping add-ons.
• Clear old site permissions: review which sites can use your location, camera, microphone and notifications.
• Understand private browsing: Incognito or private windows are useful on shared devices, but they do not hide your activity from websites, your employer, your school or your internet provider.

Clean up personal data that is already online

Prevention matters, but so does clean-up. Data broker and people-search sites may collect old addresses, phone numbers, relatives, usernames and other public-record style information into searchable profiles.

In the UK, you can ask organisations to delete personal data in certain circumstances under the right to erasure. That does not guarantee every request will succeed, but it gives you a useful route for reducing unnecessary exposure.

• Search for yourself: check your full name, old addresses, phone number, email address and common usernames.
• Remove what you can: use opt-out forms on people-search sites and data broker databases, keeping a record of what you have requested.
• Repeat the process: deleted listings can reappear when brokers refresh their datasets.
• Close old accounts: abandoned forums, shops and social profiles often contain more personal information than you remember.

Tighten your mobile privacy settings

Your phone is one of the richest sources of personal data you carry. It can hold your location history, contacts, photos, messages, payment apps, browsing activity and authentication prompts.

• Audit app permissions: remove location, camera, microphone, contacts, Bluetooth and photo access where it is not genuinely needed.
• Limit location sharing: use approximate location where possible and avoid always-on location access unless an app truly requires it.
• Install updates promptly: operating system and app updates often fix security vulnerabilities as well as bugs.
• Review advertising settings: reset or limit ad identifiers and disable personalised ads where your device allows it.
• Use built-in safety tools: on iPhone, Safety Check can help review who and which apps have access to your information. Apple’s Lockdown Mode is a stronger, more restrictive option for people at elevated risk of highly targeted attacks.

Use email aliases for sign-ups and newsletters

Your email address is one of the easiest identifiers to link across sites. If you use the same address for shopping, newsletters, competitions, forums and important accounts, it becomes a simple thread connecting your activity.

• Use aliases for everyday sign-ups: tools such as SimpleLogin, Firefox Relay or Apple Hide My Email can forward messages to your real inbox without exposing your main address.
• Keep your primary email private: reserve it for your bank, password manager, government services, healthcare, cloud storage and other high-value accounts.
• Disable compromised aliases: if an alias starts receiving spam or appears in a breach, switch it off without disrupting the rest of your accounts.

Online privacy checklist

For most people, these changes offer the best return for the least effort.

• Turn on passkeys or MFA for your main email account.
• Use a password manager for every account that still needs a password.
• Choose a reputable VPN and understand its limits.
• Keep HTTPS enabled and avoid ignoring browser security warnings.
• Separate signed-in browsing from general browsing.
• Review browser extensions and remove anything you do not need.
• Audit mobile app permissions every few months.
• Use email aliases for low-trust sign-ups.
• Opt out from major data broker and people-search sites.
• Delete old accounts that still expose personal information.
