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.
