About security
Screen lock options
To keep your phone secure, use a screen lock when it goes to sleep:
• Choose a pattern, PIN, or password to unlock.
• Add a Smart Lock to unlock automatically when connected to a trusted device, when you're
at a trusted place (like home or work), with facial recognition, or until you set your phone
down.
• You can access notifications and quick settings, start a call, and launch the camera from
the lock screen.
• You can make emergency calls on a locked phone. A locked phone still rings; you don't
need to unlock it to answer.
• If you forgot your pattern, PIN, or password, follow these steps.
You can customize the lock screen by adding your contact info. You can also control which
notifications appear on your lock screen.
NFC transfers
NFC (Near Field Communication) is a short-range wireless technology that lets you quickly
exchange information between your phone and other NFC-enabled smartphones, smart
accessories, and smart posters. You can also use NFC to tap & pay with your phone.
When you use NFC to communicate with other devices, you do so securely:
• NFC only works over a short range (a few centimeters), so it's unlikely that you'll connect
by mistake. In order to snag your NFC signal, an eavesdropper would need to be
uncomfortably close to you. And you would still have to accept the connection before
sending or receiving information.
• Your phone uses the latest security, encryption, and authentication features to protect your
personal information.
• You can turn off NFC when you’re not using it. But even when NFC is ON, it's automatically
disabled when your phone display is locked.
Along with these safeguards, exchange information only with others you know and trust.
Additional security options
For additional security, you can also:
• Protect your phone in case it’s lost or stolen. Use Find My Device.
• Connect to a virtual private network if you need to access files on a secure network.
