Most people believe hackers only chase banks and big companies. In reality, everyday users get targeted far more often because they are easier to fool. One reused password, one rushed click on a fake parcel text, or one old phone that never got updated can be enough.
The good news is that you do not need technical skills to stay safe. Most attacks work because of small habits, not clever tricks. The cybersecurity tips below follow advice from groups like the UK’s National Cyber Security Centre (NCSC), along with lessons from real breaches.
If you are brand new to this topic, read our cybersecurity for beginners guide first and then return to this checklist. Each tip explains why it matters, what to do, and where people usually go wrong.
1. Use Strong and Unique Passwords for Every Account
Why Password Reuse Is So Risky
Credential stuffing is a simple attack. Criminals take an email and password leaked from one website and try the same pair on banking, shopping, and email accounts. It works because millions of people reuse passwords. Troy Hunt’s Have I Been Pwned service has logged billions of breached accounts, so there is a good chance your email already sits in a leak somewhere.
Your email account is the most important one to protect. If someone controls it, they can reset the password for almost everything else you own. Give it a password that you never use anywhere else.
How to Create Passwords You Can Actually Remember
The NCSC suggests joining three random words, such as “purple-bridge-tractor.” It is long, easy to remember, and hard for software to guess. Avoid pet names, birthdays, and keyboard patterns like “qwerty123,” because attackers try those first.
For everything else, let a password manager do the work. It creates a different random password for each site and fills it in for you. You only need to remember one strong master password.
People worry about putting all their passwords in one place. Reputable managers encrypt your vault so the company itself cannot read it. The 2022 LastPass incident showed that a weak master password can still be a problem if encrypted vaults are stolen, so make yours long and unique.
- Use at least 12 characters for every password
- Never reuse a password across two accounts
- Skip personal details such as names and dates
- Check your email on Have I Been Pwned once in a while
2. Turn On Multi-Factor Authentication Everywhere
What Happened to Colonial Pipeline
In 2021, the Colonial Pipeline in the United States shut down for several days after a ransomware attack that disrupted fuel supply on the East Coast. Investigators said the attackers got in through an old VPN account that used a single password and no multi-factor authentication. One extra login step could have changed the story.
Multi-factor authentication, or MFA, asks for something more than your password, such as a code from an app or a physical key. Even if a criminal steals your password, they are stuck at the second door.
Which Type of MFA Should You Choose
Not all codes are equal. SMS codes are better than nothing, but SIM swap fraud can redirect them to a criminal’s phone. Authenticator apps are stronger, and hardware security keys are stronger still. Save your backup codes somewhere safe, such as printed in a drawer, so you can still log in if you lose your phone.
Start with these accounts first:
- Your main email account
- Online banking and payment apps
- Social media profiles
- Cloud storage such as Google Drive or iCloud
As more of our money moves online, as we explained in how technology is changing money, protecting financial logins matters even more.
3. Keep Your Devices and Apps Updated
The WannaCry Lesson
In May 2017, the WannaCry ransomware spread across the world and hit parts of the NHS in England, forcing hospitals to cancel appointments. It used a Windows flaw that Microsoft had already fixed two months earlier. Machines that had installed the patch were largely safe.
Updates are not only about new features and emojis. Many contain security fixes for holes that criminals already know about. Delaying them gives attackers time to strike.
Make Updates Automatic
Switch on automatic updates for your phone, laptop, browser, and router. Our Android tips and tricks article shows useful settings on your phone. Also remember that old phones eventually stop receiving security patches, which is worth checking before you buy, as covered in our smartphone buying guide.
Do not ignore small devices either. Smart plugs, cameras, and baby monitors are often forgotten, yet they sit on your home network all day. Check their apps every few months.
A trusted security app adds another layer. For example, Panda Dome antivirus offers a wide set of protection features, though any tool should support good habits rather than replace them.
4. Learn to Spot Phishing Before You Click
How Real Attacks Fool Smart People
Phishing is when a message pretends to be someone you trust to make you click, pay, or share a code. In 2023, MGM Resorts suffered a major outage after attackers reportedly phoned the IT help desk and posed as an employee, using details found on LinkedIn. No fancy hacking tool was needed, just a convincing voice.
Scams now arrive by email, SMS, WhatsApp, and phone calls. They often copy the tone of banks, couriers, and tax offices. Our full guide on how to prevent phishing attacks goes deeper into each type.
Red Flags to Check in Five Seconds
- A sense of panic, such as “your account will close today”
- A sender address that looks slightly off
- Links that do not match the real website when you hover over them
- Requests for passwords, bank codes, or gift cards
- Unexpected attachments
When in doubt, do not click. Open the official app or type the website address yourself, then check whether the message is real. Calling the company on its known number works too.
If you do fall for a scam, act fast. Change the password, tell your bank, and report the message. In the UK, you can forward suspicious emails to report@phishing.gov.uk and texts to 7726.
5. Secure Your Wi-Fi and Think Before Using Public Networks
Lock Down Your Home Router
Your router is the front door of your home network. Many people never change the default admin password printed on the sticker, which makes it easy to guess. Log in, set a new admin password, use WPA3 or WPA2 encryption, and install firmware updates.
In 2018, the VPNFilter malware infected roughly half a million home and office routers worldwide, mostly through weak or unpatched settings. Turn off remote management if you do not use it, and put smart TVs and guests on a separate guest network if your router allows it.
Public Wi-Fi and VPNs
Cafe, airport, and hotel Wi-Fi is convenient, but you cannot know who runs it or who else is connected. Attackers sometimes create fake hotspots with names like “Free Airport WiFi” to capture what you type. Avoid banking on open networks, and use mobile data when you must log in to something sensitive.
A reputable VPN encrypts your traffic and helps on shared networks. Choose a paid provider with a clear privacy policy, since free VPNs sometimes make money by selling your data.
6. Back Up Your Data Before Something Goes Wrong
The 3-2-1 Backup Rule
Backups are your safety net against ransomware, theft, and plain hardware failure. When Travelex was hit by ransomware at the end of 2019, its systems stayed down for weeks, showing how painful life becomes without recoverable data. For a home user, that could mean losing years of family photos in one afternoon.
A simple rule works well: Keep 3 copies of important files on 2 different types of storage, with 1 copy stored off-site or in the cloud. Make sure at least one backup is disconnected from your computer, because ransomware can encrypt connected drives too.
Test your backup once or twice a year by restoring a single file. A backup you never tested may fail exactly when you need it.
Prepare for Lost or Stolen Devices
Turn on screen locks and device encryption, and enable tracking before you need it. If your phone goes missing, you can follow the steps in our guide to find your lost mobile using Google and wipe it remotely if needed.
7. Share Less Personal Information Online
Oversharing Helps Scammers
Every detail you post is a puzzle piece. Your pet’s name, school, birthday, and holiday photos can help someone answer security questions or build a believable scam message. In 2021, data on about 533 million Facebook users, including phone numbers, appeared on a hacking forum after it was scraped from the platform. Even if you did nothing wrong, the less you share, the less it can leak.
Simple Privacy Habits
- Set social profiles to private and review your friend list
- Remove old apps that still have access to your accounts
- Use a separate email address for newsletters and shopping sites
- Wait until you are home to post holiday photos
Check app permissions too. A flashlight app has no reason to read your contacts or location. We shared more ideas in our article on how to avoid sharing personal information on the internet.
Families should also think about children’s habits online. Our piece on how much technology children should be allowed can help you set sensible rules.
