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 (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.

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.

For additional security, you can also:

• Protect your phone in case it’s lost or stolen. Set up your Motorola ID.
• Block all calls and text messages from a number by requesting a block from your carrier or by downloading a number blocking app from Play Store.
• Connect to a virtual private network if you need to access files on a secure network.
• Add a SIM lock to prevent others from using your cellular plan and accessing account information if your phone is stolen.
• Encrypt your phone. Encryption protects the accounts, apps, and files so that people cannot access them if your phone is stolen.
• Encrypt your SD card.
• Encrypt your SD card to ensure its files can only be viewed on this device.
• Prevent viruses and other attacks on your data and privacy with Google Play Protect.
