You do not need to be a tech expert to protect your phone, laptop and tablet. Most of it comes down to a few small habits.
This guide shows how to keep your devices safe with a short everyday routine. It covers your phone, your laptop, your tablet, and the smart gadgets around your home.
Your whole life sits on these devices: photos, messages, bank apps and work files. One weak password or one skipped update can leave a door open.
How to Keep Your Devices Safe: The Core Habits That Matter Most
Five habits cover almost everything that matters for everyday use.
| Habit | What to do | How often |
|---|---|---|
| Screen lock | PIN or fingerprint lock | Once |
| Strong passwords | A different password per account | Per account |
| Two-factor authentication | Switch it on | Once |
| Software updates | Automatic updates on | Once |
| Data backups | Backup on and checked | Monthly |
Work through your devices one at a time. Start with your phone, since it holds the most personal information.
If you are choosing a new phone, think about security before you buy. Our guide to choosing the right smartphone covers the practical points that make a device easy to live with for years.
Passwords That Actually Protect You
Your password is still the first line of defence for almost every account. A short, guessable password undoes every other safety step.
A strong password has three qualities:
- It is long. A sentence you can remember works well.
- It is different for every important account.
- It is never shared by text or email.
Your email account deserves the strongest password of all. It can reset most of your other accounts.
A password manager takes the hard work out of this. It creates long, random passwords and fills them in for you. Then you only need to remember one strong master password.
Never type a password into a site you reached through a suspicious link. If a message pressures you to log in urgently, stop, and go to the site directly instead.

Switch On Two-Factor Authentication Everywhere
Two-factor authentication, often shortened to 2FA, adds a second check after your password. It might be a code from an app, a text message, or a fingerprint.
Start with the accounts that matter most:
| Account | Why first |
|---|---|
| It can reset almost every other account | |
| Bank | Your money lives here |
| Social media | An intruder can impersonate you |
| Shopping | Saved cards and addresses sit here |
An authenticator app is generally safer than a text message code. But any second factor is far better than none.
Save your backup codes somewhere safe when a service offers them. They are your way back in if you lose your phone.
Keep Your Software Updated, Without Delay
Software updates are easy to ignore. That is exactly the problem. Updates often fix security holes that attackers already know about.
Switch on automatic updates wherever you can. Your phone and laptop can install updates overnight, and your apps can update in the background.
Now think about the devices you forget. Most homes have a few:
- An old tablet in a drawer
- A smart speaker
- A home camera
- The router itself
Check them every few months, update what you can, and retire anything that no longer receives updates.
The same rule applies to the apps you install. Remove apps you no longer use, and check app permissions too.

Back Up What You Would Hate to Lose
Backups are the safety net nobody thinks about until a phone is dropped, stolen, or wiped. A backup turns a disaster into an inconvenience.
Use the automatic backup built into your phone. Then check that it is actually running. Do this today:
- Open your settings and find the backup section.
- Confirm the last backup date is recent.
- Make sure photos and messages are included.
Keep a second copy of your most important files somewhere separate. An external drive or a trusted cloud service both work.
Backups also protect you from ransomware that locks your files. If your files are copied elsewhere, you can wipe the device and start fresh.
Stay Safe on Public Wi-Fi and at Home
Public Wi-Fi in cafes, airports, and hotels is convenient. It is also shared with strangers. That does not mean you can never use it.
On public Wi-Fi, do this:
- Stick to well-known apps and sites.
- Sign out of accounts when you finish.
- Consider a VPN if you travel often.
And avoid this:
- Logging into your bank on an open network you do not trust.
- Entering card details on public Wi-Fi.
A virtual private network, or VPN, encrypts your connection on public networks. It helps frequent travellers, but good passwords and updated software still matter more.
Your home network deserves the same care. Change your router’s default admin password, and use a strong Wi-Fi password that guests cannot guess.
Smart home devices bring real convenience. They also bring new doors into your home network. Our look at the benefits of smart home technology explains what these devices can do.

Spot Phishing Messages Before They Catch You
Many device problems start not with a hacker breaking in, but with a convincing message. Phishing emails and texts pretend to be your bank, a delivery company, or a friend.
Slow down when a message creates urgency. Watch for these red flags:
- Urgent threats, like “act now or your account closes”
- An odd sender address that does not match the company
- Strange links or spelling mistakes
- Any request for a password or code
Never enter passwords or codes from a link in a message. Instead, open the company’s app or type its website address yourself.
The same caution applies to phone calls and social media messages. A caller who claims to be tech support and asks for remote access to your computer is almost certainly running a scam.
No genuine support team calls you out of the blue. Hang up, and contact the company through its official number if you are unsure.
Before You Sell, Give Away or Recycle a Device
An old phone or laptop still holds your photos, messages, and saved logins, even after a quick delete. Before a device leaves your hands, run through this checklist:
- Back it up first.
- Sign out of your accounts.
- Wipe it with the factory reset option, and remove any memory cards.
- Remove the device from your account’s trusted list online.
Check that the reset actually worked. Set the device up briefly and confirm your accounts are gone.
If a device no longer works at all, take it to a proper electronics recycling point. Wipe old hard drives and USB sticks before disposal too.
Looking after your devices also means looking after their physical health. Our guide to cleaning a washing machine shows the same principle at work in the home.
What the Bigger Security Picture Looks Like
Everyday device safety and business cybersecurity share the same foundations: strong access controls, regular updates, and backups.
If you are curious about how larger organisations think about these problems, our comparison of cybersecurity frameworks explains the ideas in plain terms.
For official, up-to-date guidance, the UK National Cyber Security Centre publishes clear advice for individuals and families. Checking a trusted source beats trusting a random tip from social media.
The goal is not to become paranoid about every click. It is to build a routine that runs quietly in the background.
Frequently Asked Questions
What is the first thing I should do to protect a new phone?
Set a strong screen lock and a unique password for the account tied to the phone. Then switch on two-factor authentication and automatic backups. After that, turn on automatic updates and check your app permissions.
How often should I update my devices?
Let your devices update automatically. That way you are protected as soon as a fix is released. If you prefer manual updates, check at least once a week.
Is a free password manager safe to use?
Yes. A well-known password manager from your phone maker or browser is a good starting point. It is far safer than reusing one weak password everywhere.
Should I use public Wi-Fi at all?
Public Wi-Fi is fine for browsing and streaming. Just avoid banking or entering card details on a network you do not trust. Sign out of accounts when you finish.
What should I do if I clicked a suspicious link?
Do not panic. Do not enter any passwords or codes on the page that opened. Close the page, and run a security scan if your device offers one.
Change the password of any account you may have exposed, starting with your email.
