Business Banking Authentication App

We've now switched to our new and secure Business Banking Authentication App. You'll need the app when using Business Internet Banking to:

  • Setup new UK recipients
  • Setup new Standing Orders
  • Setup new International Payments recipients

The app comes with enhanced security, including fingerprint & Face ID login on compatible devices. You’ll also be able to register multiple devices, no more forgetting your device at home or the office.

To keep your business running smoothly, download the app now. Here’s how:

Download and activate

Our new app is available now on iOS and Android. Search for “TSB Business Auth app” in the App Store or Google Play or follow the links below using the device you wish to download the app onto. 

App Store Google Play

Once you’ve downloaded the app, open it and enter:

  • your user ID
  • password
  • three characters of your memorable information

You’ll then need to select a number for us to send you an activation code by text or phone call to activate your app. If your phone numbers need updating, you can do this with Business Internet Banking. Just go to 'Change details', 'Change phone number' and type in your latest details.

Once you've setup your device, you'll then only need to enter three characters of your memorable information to get into the app - or just your fingerprint or Face ID if you've got this setup.

There’s a handy video on this page that shows you how to get all setup, so give it a watch.
