Online Banking technical support​

Our aim is to make Online Banking easy to access for all our customers, which is why we've pulled together this guide of supported browsers and troubleshooting tips.

Troubleshooting tips

As part of our Online Banking security, we ask you if we can 'recognise your device'. This means we can be more confident that it's really you logging in.

If we don't recognise the device/browser you're using, we'll send you a One Time Access Code by text message to allow you to log in. This means that no one else can log in to your account from a device that you haven't asked us to recognise.

To recognise your device, we store a small security token in your internet browser. This doesn't hold any personal information about you, it simply allows us to recognise your device when you use it to log in to Online Banking.

If you continue to see the 'We don’t recognise this device' message, check our suggested ways to solve this issue.

Apple OS updates in September 2017: Due to a change made by Apple to their iOS 11 & macOS 10.13 operating systems in September 2017, we will now ask you if we can ‘recognise your device’ again if you haven’t logged in to Online Banking for 30 days or more. There is no impact to the Tesco Bank mobile application.

      Below are some instructions to tell you how to enable cookies on some of the most common internet browsers. Just skip to the browser you use and follow the instructions.

        To enable cookies in Internet Explorer

        • Select Tools from the top menu, and then click Internet options
        • Click the Privacy tab
        • Click Advanced
        • Select 'Override automatic cookie handling' under the 'Cookies' section in the Advanced Privacy Settings window
        • Select the 'Accept' or 'Prompt' option under 'First-party Cookies'
        • Select the 'Accept' or 'Prompt' option under 'Third-party Cookies' (if you select the 'Prompt' option, you'll be asked for approval every time a website attempts to send you a cookie)
        • In the Internet Options window, click OK to exit

        To enable cookies in Google Chrome

        • Click the Chrome menu/burger icon on the browser toolbar
        • Select Settings
        • Click Show advanced settings
        • Click Content settings in the 'Privacy' section
        • Select Allow local data to be set to allow both first-party and third-party cookies - if you only want to accept first-party cookies, check the box next to 'Block all third-party cookies without exception'

        To enable cookies in Mozilla Firefox

        • Select Tools from the top menu
        • Click Privacy in the top panel
        • Set 'Firefox will:' to Use custom settings for history
        • Check the box next to 'Accept cookies from sites' to enable cookies
        • Click OK

        To enable cookies in Apple Safari

        • Open the Safari menu on the browser toolbar
        • Select Preferences
        • Click Security in the top panel
        • Under 'Accept Cookies' select Only from sites you navigate to

        If you use Private or Incognito browsing, any cookies that are set during that session will be deleted automatically when you close your browser. This means that we'll not be able to recognise your device the next time you use that browser, and we'll have to send you a One Time Access Code to allow you to log in.

        Similarly, if you choose to manually clear your cookies, we'll not be able to recognise your device the next time you try to log in.

          The security token we use to recognise your computer is stored within your internet browser. If you use more than one browser (for example Firefox and Chrome) you'll have to ask us to recognise each of them.

          If you change or upgrade your browser, we may have to send you a One Time Access Code the first time you use the new version to log in.

            If you installed security software (such as Norton or McAfee), it may be set up to block us from confirming if you're using a computer that you've asked us to recognise.

            You'll normally find the settings under Privacy in your security software, and you should check that the software isn't blocking our site. If you have the option to add trusted sites to your security software, you should add either tescobank.com or, for software that needs only the log in address, add login.myproducts.tescobank.com.

            If you need more help, please refer to the instructions provided by your security software to find out how to check your settings.

              Supported browsers

              We maintain a focus on our customers' needs, including which browsers and devices are being used to access Online Banking, so that we understand what we should support and why.

              We support the latest versions of:

                • Internet Explorer
                • Microsoft Edge
                • Chrome
                • Firefox
                • Safari

                We also support the latest default browsers on Apple iOS and Google Android devices.

                  You can find out which version of the browser you are using in the about browser information:

                    Internet Explorer

                    From the Help menu, select About Internet Explorer.

                      Google Chrome

                      From the options menu, which is the button to the right of the address bar, select About Google Chrome.

                        Mozilla Firefox

                        From the Help menu, select About Firefox.

                          Safari (for Mac)

                          From the Safari menu, select About Safari.

                            If you're using a modern and up-to-date browser, you shouldn't have any problems accessing Online Banking, although sometimes you may find some features don't work quite as you expected. This is something we are continually trying to improve.

                            If you're not using an up-to-date browser to access the internet, it's important that you upgrade. A newer browser will offer many benefits, including better performance and increased security. Have a look at the list of popular browsers we recommend.
