Help protect your phone & data
Set a PIN, password, or pattern
You can help secure your phone by setting a screen lock with a PIN, password, or pattern. When you turn on your phone or wake up its screen, you’ll need to enter your PIN, pattern, or password to unlock it. On many phones, tap Settings 
Decide when your phone can stay unlocked
To let your phone stay unlocked in certain situations, like when you’re in a specific place, you can turn on Smart Lock. If your phone is on Android 10 and above, you can let your phone stay unlocked after you unlock it once. On many phones, tap Settings
Be ready to find a lost phone
To be prepared in case you lose your phone or tablet or Wear OS watch, check that Find My Device can find it. Your phone must be signed into a Google Account, turned on, and connected to the internet to remotely use Find My Device. Learn how to check that Find My Device can find your phone.
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 phone's lock screen. This can help someone return your missing phone. Learn more about information on your lock screen.
Encryption can help keep your data safe. Many up-to-date phones are encrypted by default.
If your phone isn't encrypted by default, and is using Android 4.1 and up, you can choose to encrypt the data on your device. On many phones, tap Settings
Help stay safe online & with apps
Some apps can harm your phone. 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 Play Store app installed, and you download apps from other sources, Play Protect scans those apps before and after you install them. If you see a warning from Play Protect, we recommend not installing that app. Learn more about protecting your phone against harmful apps.
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. Learn more about 2-Step Verification.
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. Manage your account access and security settings.
Although most ads are safe, you can potentially affect your phone 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 phone, we recommend that you download and install it. Get the Chrome app on Google Play.
