SECURITY

Screen Lock

Settings > Security & Biometrics > Screen lock
It is recommended that you secure your device using a
Screen lock. This added level of security helps prevent
someone from accessing your device including your
personal data, apps, and email accounts. There are a
variety of screen lock types with different levels of security
for your selection including a swipe, a pattern, a numeric
PIN, a password, or face unlock.
In addition, you can set a Smart Lock to unlock your
device automatically and keep it unlocked when you are in
a trusted location or when trusted devices are detected.
