Netflix finally allows you to protect your profile with a PIN. This is very useful if you have children who use your account. You can lock your adult profile with a PIN, ensuring children can only use their own profile.
To find this option, visit the Netflix website, mouse over your profile icon in the upper-right corner of the screen, and click “Account” to find your account settings.
If you like, you can also activate “Requires [Name] PIN to add a new profile.” This will prevent people from creating a new profile on your Netflix account unless they know your PIN.
Click the “Save” button to activate the PIN you chose.
With Netflix parental controls, you can also filter content based on age ranking by profile. Click the “Change” button next to “View restrictions” above the “Lock profile” option for the account on the Account settings page to access this option
Now, with a PIN, you can make sure children will stick to their own profile and not step back and open your profile.
