Step 1: Setup environment

Go to Settings → Accounts → Family & other users

Add a local account (no Microsoft login required)

Set the new account type to Standard

Login and setup the NSFWLocker here

Step 2: Install

Download from Gumroad. Right-click the installer and choose "Run as administrator."

Step 3: Activate Locker

Enter your license key and set your lock duration by right clicking the taskbar tray icon. Once active, the timer can't be bypassed without uninstalling — which requires admin access.

Step 4: Lock Admin Account

- Generate a long, random password
- Create a new email (ProtonMail recommended)
- Email the password to yourself with a delay (use Gmail + Boomerang, or LetterToMyFuture)
- Log out and only use the Standard User

Step 5: BIOS Lock (Extreme)

- Reboot → Enter BIOS (F2, Del, etc.)
- Set a Supervisor or Admin password
- Send that to your future self, too
- This blocks USB boot, safe mode, or OS reinstall

Step 1: Setup Family Link

- Install Family Link for Parents on a second device
- Create a parent Gmail with a random password
- Send that password to your future self

Step 2: Block Everything

Use Family Link to:
- Block browsers, YouTube, access to Settings
- Disable app installs and Chrome exceptions

Step 3: Fully Kiosk App

- Install Fully Kiosk Browser
- Lock the device to selected apps only via universal launcher
- Disable status bar, home, and recents and enable kiosk mode.

Step 4: Enable Knox (Samsung)

Samsung Knox allows full enterprise lockdown (disable safe mode, factory reset, etc). DM me on Discord if you need help configuring it.

Step 5: Install Bulldog Blocker

Install a screen-monitoring app like Bulldog blocker (really good app) to detect and blank out NSFW images anywhere on screen, even in apps.

Step 1: Screen Time Passcode

Settings → Screen Time → Use Screen Time Passcode. Choose something you won’t remember or give it to someone you trust.

Step 2: Block NSFW Content

Settings → Screen Time → Content Restrictions → Web Content → Limit Adult Content. You can also block Safari or YouTube entirely.

Step 3: Disable App Access

Disable app installation/deletion and block specific apps under "Allowed Apps".

Step 4: Downtime Mode

Set a strict Downtime schedule and restrict apps to a bare minimum.

Step 1: Cut the Wi-Fi Hardware

Open your PS4 (warranty sticker covers the screws), locate the Wi-Fi chip, and unplug the antenna cable. This disables all internet connectivity.

Step 1 (Alternative): DNS Blocking

Change DNS settings to 127.0.0.1 or use OpenDNS family filters to block online content via router.

Step 3: Lock with Parental PIN

Enable Sony's built-in parental controls and set a passcode to restrict browser use and app changes.
