Welcome to the Community!
If you are referring to the 4-digit TiVo® PIN, to watch shows during the day that were recorded after the watershed of 21:00, you will usually be expected to enter your PIN.
You can choose to disable most PIN requests, although programmes from some channels will always require a PIN based on the age-classification for the content.
To modify your parental controls for the PIN, head on over to: -
HOME > HELP AND SETTINGS > PARENTAL CONTROLS (ENTER PIN) > REQUEST A PIN TO WATCH RECORDINGS
If this is currently set as "Request a PIN...", then you can change this to "Do not request a PIN".
Hope this helps,
