Encryption stores your data in a form that can be read only when your phone or tablet is unlocked. Unlocking your encrypted device decrypts your data. Encryption can add protection in case your device is stolen.
- All Pixel phones are encrypted by default. So are Nexus 5X, Nexus 6P, Nexus 6, and Nexus 9 devices.
- You can choose to encrypt Nexus 4, Nexus 5, Nexus 7, and Nexus 10 devices.
To get the most protection for your data on an encrypted device, always require your PIN, pattern, or password to unlock your device when it starts. Learn how to set a screen lock.
Understand what data gets encrypted
On an encrypted device, all personal data gets encrypted. This includes things like your email, texts, contacts, Google Account data, app data, photos, media, and downloads. Some non-personal data, like file sizes, aren't encrypted.
Decrypt your data using accessibility features
To help you enter your PIN, pattern, or password to decrypt your Pixel phone at start-up, you can use TalkBack, Switch Access, and other updated accessibility services. Pixel phones can't use Bluetooth-paired accessibility devices until after you decrypt.
On encrypted Nexus phones and tablets, if you choose to require your PIN, pattern, or password at start-up, you'd need to enter it without help from either accessibility services or Bluetooth-paired accessibility devices.
Encrypting your Nexus device may take an hour or more, and your device may restart several times. If the process gets interrupted, you might lose the information on your device. We recommend these steps before you start:
- Schedule an hour or more.
- Plug your device in to charge.
- Know which Android version your device is running. Learn how to check.
- Open your device's Settings app.
- Tap Security or Security & Location Screen lock.
- To choose your screen lock, tap Pattern, PIN, or Password.
- You'll be asked to "further protect this device" by requiring your PIN, pattern, or password when your device starts. The first time that you choose this setting, it will encrypt your device.
- Select Require to start device.
- Tap Continue.
- Set your PIN, pattern, or password. Follow the on-screen steps.
You can choose whether to require your PIN, pattern, or password when your device starts. Learn how to set a screen lock.
