How to Setup User Account on the Device
Tap Settings | Security | ADD USER
Tap Set up now (the screen goes dark for 10-15 seconds at this step)
Now you're back at the home scren and will see an icon for the new profile
Configure the User Account
Tap the icon for the new profile
Tap the > on the Welcome screen
If the user has a Google Account you can input their credentials and they can have all of their email, calendar, and apps available on your tablet.
You can also create an account on the device that isn't associated with a Google Account . That's what I did for my younger children.
For the rest of this article, I'm going to assume we're configuring this for a child too young for a Google Account.
If the user doesn't have a Google Account, tap No.
Tap Not now if you don't want to create a Google Account.
Accept the defaults and tap the >.
Input a name for the tablet user account.
Accept the terms and tap the >.
The user account is setup.
Since the kids the kids will only be using this for games I took all the shortcuts and widgets off the Home screen.
If you'd like, now might be a good time to help them select a "login" pattern (Settings | Security | Screen Lock | Pattern)
Connect to Play Store
I didn't want to re-purchase any games, so I connected my children's accounts to an account that already had a number of games associated with it.
Tap the Play store icon, Existing, and Sign in
Tap OK and give the device a minute to Sign in.
Secure Play Store
I've had experience with kids buying apps without realizing they were spending real money (if you've purchased anything in the Google Play store your credit card is linked with your Google Account). Here are some easy steps to lock it down.
In the Google Play app, tap the three dot menu icon, tap settings and look for the User Controls section.
Tap Use PIN for purchases
Tap Set or change PIN and create a 4 digit code.
I also wanted some limits on the apps that could be downloaded.
Tap Content filtering and select an app rating and tap OK
I didn't want contacts, email, or calendar to be easily accessible in this user account so I turned off sync on most of the Google Services.
Tap Settings | Accounts | Google and uncheck the services you don't want sync'd in this account.
