If you get locked out from Online Banking or need a temporary security number, it is possible to reset your access yourself online.
If you have blocked either your password or security number and are using a recognised device, simply click on ‘forgotten password or security number’. You will then be asked for your personal information and to answer some security questions.
Once completed, a One Time Access Code (OTAC) will be text to your mobile. Please enter this when prompted and you will then be able to reset your security information and access your Online Banking.
If you have blocked either your password or security number but are using an unrecognised device, then you will need to contact us to request a temporary security number.
- call the Online Helpdesk on 0345 300 3511 (open 24 hours a day) who will be able to text this to you
- send a private message via Your Community to our private @Tesco-Bank account and we can arrange for a temporary security number to posted to you within 3 - 5 working days
- message us via our social media channels Facebook Messenger or Twitter and we can arrange for a temporary security number to be posted to you within 3 – 5 working days
If you are using a device that was previously recognised by us and are unsure why this has changed, this is usually because you have deleted your browsing history. We recognise a customer’s device from the cookies in your web browser and when these are cleared we are unable to do this, so you would need to register the device again.

Abroad again, locked out of the app again. After the last time of getting stressfull texts throughout the night then not being able to access my account, then waiting ages to speak with someone and still no call back from anyone... I'm about to call it a day with you I think. Even having to register on here - which in case nobody at the bank realises unleashes a further serious security flaw. Oh, and even when I'm sitting at home on my PC the website says it's an unrecognised PC because it relies on simple cookies! Ah well, not worth the frustration. I'll phone up again once in the UK - this time will log a complaint - then maybe it really is time to bail before it sinks? By the way - for anyone thinking of following the bank's advice to message them on here under such circumstances I'd like to point out their T&Cs in relation to this: "SecurityWe do not warrant that Your Community is secure, free from bugs, viruses, interruptions, errors, or other limitations.

How can I send a PM to CNET. This is the most confusing website in the world to use. Noting is simple, I keep getting locked out. I just want to pay my bill.
