Keep your Android device safe
You can help keep your Android device secure by using a screen lock, 2-step verification, and other Android security features. In case your phone gets lost, you can be prepared with Android Device Manager.

Note: Not all Android devices have settings in the same place or with the same names. For your specific device's settings, see your manufacturer's support site.
Set a PIN, password, or pattern
You can help secure your device by setting a screen lock with a PIN, password, or pattern. When you turn on your device or wake up its screen, you’ll need to enter your PIN, pattern, or password to unlock it. On most Android devices, tap Settings Security Screen lock.
Set automatic unlock
If your device is running Android 5.0 and up, you can have your device automatically unlock in certain situations, like when you're in a specific place. In other situations, you'd use your PIN, pattern, or password to unlock your device.
Be ready to use Android Device Manager
If your lost phone is signed in to a Google Account, powered on, and connected to the Internet, you can remotely find, lock, and erase it with Android Device Manager.
Put contact information on your lock screen
You can put contact information (like an email address or phone number that you don’t mind sharing) on your device's lock screen. This can help someone return your missing device. On most Android devices, tap Settings Security Owner info.
Encryption can help keep your data safe. Many up-to-date phones are encrypted by default.
If your Android device isn't encrypted by default, and is running Android 4.1 and up, you can choose to encrypt the data on your device. On most Android devices, tap Settings Security Encrypt phone.
Some apps can harm your device. To avoid harmful apps, you can download from trusted sources, like Google Play. Before an app gets published to Google Play, the app is reviewed to make sure it's not harmful.
If you have the Google Play app installed, and you download apps from other sources, the Verify Apps feature scans those apps before and after you install them. If you see a warning from Verify Apps, we recommend not installing that app.
Turn on 2-Step Verification
You can use 2-Step Verification to help protect your Google Account with both a password and a code from your phone. In case someone gets your password, you'll have another layer of protection.
Make a Security Checkup
To help protect your Google Account, you can update how you sign in, your recovery options, and how we should contact you if we notice something suspicious.
Although most ads are safe, you can potentially affect your device by opening some banner ads or ads that open in new windows ("pop-ups").
Beware of anything that claims that your phone is infected or asks for your password or personal information. You could accidentally download unwanted or potentially harmful software or give someone access to your account.
Chrome is built with security in mind and has frequent updates to help keep you safe. If you don’t have Chrome on your device, we recommend that you download and install it.
