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 Security Screen lock.
Decide when your phone can stay unlocked
If your phone is using Android 10 and up, you can let your phone stay unlocked after you unlock it once.
On some phones, 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 find a lost phone
If your lost phone is signed in to a Google Account, is turned on, and connected to the Internet, you can remotely find, lock and erase it with Find My Device.
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.
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 Security Advanced Encryption & credentials Encrypt phone.
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.
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 Check-Up
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 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.
