1. Screen time to disable browser, App Store etc.
2. Type random 4-digit passwords until you forget.
3. Use your own Apple account as reset.
4. Remove apple password from password manager. Store in “Notes” app or similar on computer.
5. Lock this app storing password behind mandatory typing of gibberish using Cold Turkey on desktop.
Works well for me.
I will mention that as a younger person who grew up with internet access, I get the feeling that the “just be disciplined” comment often comes from people who didn’t have these addictive habits seared into their minds from an early age or have fought them off and forgotten what it’s like to literally lose control of your actions, especially when its normalized around you.
I’ve noticed a lot of older people don’t see the internet as a threat in the same way as I do, and I envy that.
Living with phones like this is completely unnatural.
