If your child's setting uses a PIN code to sign children in and out, you'll need your personal sign-in PIN code to do this.
To find your PIN code:
Tap your profile picture in the menu bar
Tap Sign-In Pincode
A pop-up will appear showing your personal PIN code, which you can use to sign your child in and out on the sign-in screen.
💡 This option will only appear if your setting has enabled PIN code sign-in. If you can't see it, check with your setting
Please note that your PIN code is strictly personal as it links you to any actions performed on the sign-in screen. It cannot be changed.
