Adjustable intervention duration and passcode lock for onesec settings

Hi one sec team,

I’m writing to suggest an update to the "Customization Lock" feature (intervention for opening onesec settings).

Considering the latest changes in iOS 26.4, in order to keep the app very effective and prevent "impulse editing" of settings (the only possibility to bypass the restrictions if we use a screen time password), I would like to have more restrictive options:

Customizable Intervention Time: Currently, the breathing exercise is too short/fixed. I would like the ability to select a much longer duration for the intervention before settings can be modified (like 1/2/3/5 minutes).
Passcode Protection: An option to lock the settings behind a specific passcode (ideally different from the device passcode). This could restrict heavily the access, just in case.

Since I’m a premium user, I would like to keep using one sec as my only tool, but without these "strict mode" enhancements, I have to use another app to block onesec in order to prevent me to access onesec settings.

Thanks for your help!
