Fortnite is loved by teens, but buying in the app for skins and emotions can leave parents with hundreds of dollars. If you're worried about over-spending, Android users can lock down Fortnite child purchases with these steps.
A warning word before you begin. Because Fortnite is not part of the Play Store, Fortnite completely bypasses Google's own parental controls. This means that all parental controls that you have already used in Google Play simply won't work.
Creating a New Fortnite Epic Games Account
When you install Fortnite, you will be prompted to create or login to an Epic Games account. If you already have an Epic Games account, creating a new account for your kids to use with Fortnite instead will be the fastest solution to prevent unauthorized purchases.
To start, open the Fortnite app and wait for the charging to finish. You will be asked if you have played Fortnite before. Even if you have it, click on "No."
Complete the form, tap the check box to confirm that you accept the terms of service, and then select "Create Account" at the bottom.
Fortnite will sign in with your new account, but you must press "Accept" to confirm that you accept the license agreement before The login process is complete.
Once a new account is created, you do not need to do anything else. Just don't link any payment information like a credit card or PayPal to your new Epic Games account. Without this information, your child will not be able to make any purchases in the app.
Of course, this isolationist method may not be for everyone. If you want to treat your children to V-Bucks (Fortnite app currency), you must add your payment information.
Setting a PIN in Fortnite
If your Epic Games account has your payment information attached, you can restrict purchases by adding a PIN with the built-in parental control.
To start, open the Fortnite app and wait for it to load. Click on the menu button in the upper-right corner of the play screen, then select “Parental Controls.”
Press "Set Parental Controls" at the next screen.
You will be asked to confirm if you want to use your Epic Games email address to manage your PIN. Click "Change Email" if you prefer to link your parental controls to another email address. Otherwise, select "Next."
In the next step, select a six-digit PIN. Make sure this is not something your children can easily guess. Type it twice (a second time to confirm) and then press "Next."
The next screen offers various typical parental controls, including options for restricting chat and filtering obscene language.
You cannot apply purchase restrictions at this time, but press "Save" to save your PIN to your account.
Your PIN is now saved and active, but you must now enable purchase restrictions for your Epic Games account.
Limit purchases with PIN in your Epic Games account  With a PIN applied to parental control, you must go to your Epic Games account settings online to restrict purchases. You can do it from any browser.
Go to your Epic Games account area and log in. Scroll to the bottom and click "Turn on Parental Controls." You will be asked to enter the PIN you created in the Fortnite app.
Click "Manage Store Settings" and re-enter your PIN. Toggle "Always require a PIN for purchase" and then click "Save" to confirm.
With the restrictions in place, you try to make any purchases you (or your children) now in your Epic Games account will require your PIN, including any purchases made in the app via Fortnite self.
