We have just released an update to the More TV app TalkTalk TV box which will result in your saved PIN being stripped from the app.
This is a one-time issue and future More TV updates will not unsave your previously saved PIN. You can save your PIN again and it will be kept. We apologise for the inconvenience.
I no longer remember my TalkTalk PIN number
If you have forgotten your TalkTalk PIN number, please visit the MyAccount website and sign in with your MyAccount details. You will be able to find your PIN number by selecting the ‘My services’ tab and then ‘View/change TV PIN’. (if you’re already signed into MyAccount, this link is a shortcut to the view PIN page).
