Encrypting your smartphones has gotten fairly easy in the past few years. Some phones even come encrypted by default, which is great. An encrypted phone works no different than a non-encrypted phone, and you won't notice anything weird after setting it up.

Encrypting a phone means that if it falls into an attackers hands, they won't be able to read your data, even if somehow someone could bypass the lock screen (not legitimately unlock it).

With an Apple device, simply setting up that passcode turns on the encryption.

Make sure your device is on a charger (it takes some time to encrypt).

  1. Settings app
  2. Security
  3. Encrypt phone

Encryption requires your same lock code as the one used on your lock screen. If you have a rooted phone, you can use Cryptfs Password to change the encryption password to something different than your lock code.
