How you can protect your devices

We take your security seriously.

Following some simple steps to protect your devices can help keep your accounts and identity safe from fraudsters' attempts.

When you’re online

  • Protect your computer and mobile devices with up-to-date security software and install regular security and software updates.
  • Keep your operating system up to date and always use an up-to-date Internet browser - find out more about the browsers we support when using Online Banking.
  • Check a website is secure before you enter any account or card details. Look for the 'https' at the start of the web address and the padlock or unbroken key icon next to the address bar.
  • Do not enter your security information on a website you have accessed via a link in an email or text message.
  • Avoid using non-secure or unencrypted Wi-Fi, as fraudsters can set up malicious Wi-Fi networks that could intercept your data.
  • Use public Wi-Fi hotspots only if you know they are trustworthy.
  • Avoid downloading attachments or clicking links from unsolicited emails - please forward any suspicious emails from Tesco Bank to
  • Only download apps, files and programmes from sources you trust.
