Overview

Online banking fraud costs UK consumers millions annually. Most attacks exploit weak passwords, unsecured networks, or social engineering rather than breaking bank encryption.

Step 1: Secure Access

How you connect to your bank matters.

1

Use Secure Connections Only

Only access banking on your home Wi-Fi or mobile data
Never use public Wi-Fi for banking, even with VPN
Ensure your home Wi-Fi uses WPA3 or WPA2 encryption
Consider using your bank's mobile app instead of browser
Mobile apps have built-in security that browsers lack

2

Strong Authentication

Use a unique, complex password for banking (16+ characters)
Enable two-factor authentication (2FA), mandatory for UK banks
Use biometric login (fingerprint/face) on mobile banking apps
Never share one-time passcodes with anyone, including 'bank staff'
Your bank will NEVER ask for your full password or PIN

3

Bookmark Your Bank

Type your bank's URL directly or use a bookmark
Never click banking links in emails or text messages
Verify the URL shows your bank's correct domain
Check for the padlock icon and HTTPS
Log out completely when finished, don't just close the tab

Warning:

Banks will never send you a link asking you to verify your account. If you receive one, it's a phishing attempt. Contact your bank directly using the number on your card.

Step 2: Device Security

Keep the devices you use for banking locked down.

1

Keep Devices Updated

Install OS updates immediately when available
Keep your browser updated to the latest version
Update your banking app when new versions release
Enable automatic updates on all devices
Don't use banking on jailbroken or rooted devices

2

Secure Your Device

Use a screen lock (biometric preferred)
Enable device encryption (BitLocker on Windows, FileVault on Mac)
Install reputable antivirus software
Don't install apps from unknown sources
Regularly scan for malware

Step 3: Monitor Your Accounts

Catch fraud early by monitoring activity.

1

Set Up Alerts

Enable transaction notifications via your banking app
Set alerts for transactions above a threshold you choose
Enable login notifications for new device access
Set up balance alerts for low balance warnings
Review all notifications promptly

2

Regular Account Reviews

Check transactions at least weekly
Review direct debits and standing orders monthly
Look for small unfamiliar transactions, fraudsters test with small amounts
Report anything suspicious to your bank immediately
Keep bank's fraud hotline number saved in your phone

3

What to Do If Compromised

Call your bank's fraud team immediately (number on back of card)
Lock your card via the banking app if available
Change your banking password from a secure device
Report to Action Fraud (actionfraud.police.uk)
Monitor statements closely for the following 3 months
