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.

Be prepared in case your phone goes missing

Be ready to find a lost 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.

Encrypt your phone

Encryption can help keep your data safe. Many up-to-date phones are encrypted by default.

Help stay safe online & with apps

Download apps from trusted sources

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.

Update your account verification, access & security settings

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.

Be careful about the ads you tap

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.

Try Chrome as your browser

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.
