You can set parental controls to restrict access
to certain content on GeForce NOW. Parental controls use your regional
content ratings to restrict access (ESRB for USA, PEGI for Europe, and
USK for Germany.) To set parental controls, go to the Settings
row and select Parental controls
.
You will then see a list of options that define the restriction level. (The example below shows content ratings for ESRB),
Everyone (0+)
Everyone (10+)
Teen (13+)
Mature (17+)
Allow all content (on by default)
Select a restriction level and then "OK." Restricted content will require you to enter a personal identification number, or PIN. You can also choose to hide restricted games.
Restricted games are hidden by default. Uncheck
the "Hide restricted games" box to show restricted games. Restricted
games will appear with a 
symbol.
Selecting a restricted game from GeForce NOW will prompt you for
the PIN. If the PIN is successfully entered, select "Continue"
to play one session, which will re-lock after you exit the game, and "Unlock
for 30 minutes" to keep the session unlocked for 30 minutes, after
which the game will be re-locked.
NOTE During initial setup of your membership
billing details, you will be asked to set up a PIN which is also used
to set the parental controls.
