To restrict access to a specific profile on your account, you can protect it with a Profile Lock PIN. If you have already accessed a profile and get prompted to enter a PIN before playing a TV show or movie, see
more about account-level PINs.
To add a PIN to a specific profile:
From a web browser, go to your Account page.
Open the Profile & Parental Controls settings for the profile you want to lock.
Change the Profile Lock setting.
Enter your Netflix account password.
Check the box to Require a PIN to access the selected profile.
To remove the PIN requirement, uncheck the box.
Enter 4 numbers to create your Profile Lock PIN. Unless you're using an unsupported device, you'll enter this PIN to open the profile or play titles downloaded from it.
To require a PIN any time a new profile is added to your account, select Require PIN to add new profiles.
This option is only available after creating a Profile Lock PIN for the main account profile.
If you forget your Profile Lock PIN, click the Forgot PIN? link on the bottom of the screen. If you’re watching on a TV, enter the provided web address into a web browser.
To view or edit the Profile Lock PIN that was created for the profile, enter your Netflix account password.
