“How do I password protect my PS Vita?”
Before you can lockdown your PS Vita you’ll need to set a 4 digit passcode. This passcode will be used to unlock the PS Vita when turning it on or coming back from standby mode.
1. Tap ‘Security’ -> ‘Screen Lock’ -> type in a 4-digit number. Do not forget this number.
2. Tap the checkbox so that a checkmark appears. Now the PS Vita will require this passcode whenever you turn it on or come out of standby mode.
