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'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.


We'll send the Temporary Security Number to you by text message, if we have your up to date mobile phone number. If we don't, we'll send it by post and you'll have to wait for it to arrive before you can log in to Online Banking.


When you receive your Temporary Security Number return to the Registration or Login screen. You'll be asked to enter the Temporary Security Number in full to complete registration or reset your login details.


Your Temporary Security Number is valid for 30 days from the date it was requested and can only be used once. If it expires, you'll need to contact us to get a new one.

I messaged CET requesting a temporary security number but it removed the information from the message?

That's right @gmax07, if you don't add spaces between the characters of your details, the information is redacted. I can see that everything has been sorted for you now though. 


What information do I need to fone up to activate my new card as can't remember my username and details please.

You'll just need the card number to activate this @Babygirl62. Just call the number on the sticker attached to the card and you can follow the instructions to get that activated :) 


I have forgotten my password and locked my account, both for the app and my laptop is not recognised.

Could i have a temp security number, and an idiots guide would be helpfull..........


Hi @WasP, send us your name, DOB and postcode in a private message to our @CET account and we can post out a new security code. 


When you send your DOB and postcode, add additional spaces between the characters, like A B 1 2 C D etc! 


Please can I have a temporary security code? Thanks

Please follow the instructions above, @sclegg75.


@AshleighB I would if I knew how to  send a PM!! 😁





I am locked out of my account.  I did receieve a code by text.  Please
