Question:

  • How do I encrypt data on Android devices?

Background:

Encryption ensures that data is secured against any theft of the device. Encryption is tied to passcode or fingerprint security.

Recent Android devices encrypt data by default. To check encryption status:

  1. Go to Settings > Security (or Settings > Security and Location).
  2. Scroll to the section headed Encryption > Encrypt phone.
  3. An encrypted device displays Encrypted.

Procedure:

To encrypt an Android device:

  • Be aware that this process may take an hour or more.
  • Back up data - if the process is interrupted, data may be lost.
  • Plug the device in to charge.

Android 5.0 and 6.0

Go to Settings > Security (or Settings > Security and Location).

  1. Tap Screen Lock.
  2. Tap Pattern, PIN, or Password.
  3. Choose 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, and then tap Continue.
    • Set a pattern, PIN, or password.
  4. After encryption is completed, you can choose not to require the security when your device starts. However, Trustwave recommends that you keep this extra security.

Android 4.4 and below

  1. Go to Settings > Security (or Settings > Security and Location).
