What is a Temporary Security Number and when do I use it?

A Temporary Security Number is a code we use as an additional security measure to confirm your identity if:

  • You're registering for Online Banking for the first time
  • You’ve forgotten your login details
  • You've locked your security number, you're using a browser on a computer or mobile device we don't recognise and we don't have your up to date mobile phone number
  • You've locked your password, you're using a browser on a computer or mobile device we don't recognise and we don't have your up to date mobile phone number.

If you know your security number and security questions, it is possible to call us on 0345 300 3511* and update your mobile number.

Calls may be recorded. *This number may be included as part of any inclusive call minutes provided by your phone operator.

Hello can you please send me a temporary security code as I cannot log into my loan account,  saying it doesn't recognise device.

Hi @Javadfallahi77, we can send you a Temporary Security Number (TSN) through the post which will reset your online banking and allow you to get logged in again. This can take between 3-5 business days to arrive and will be valid for 30 days – if you would like me to arrange this for you, please send a private message to @Tesco-Bank.

 

Alternatively, you can call our Online Helpdesk anytime on 0345 300 3511 and request a TSN to be sent by text immediately once security is completed - Thomas
