Most newer Android phones ship with encryption already turned on by default. Things to Consider Before Enabling Encryption An attacker won’t be able to access the data without the encryption key, although there are more advanced cracking methods that make it a possibility. For example, corporations with sensitive business data on company phones will want to use encryption (with a secured lock screen) to help protect that data from corporate espionage. (On Android 5.1 and above, encryption doesn’t require a PIN or password, but it’s highly recommended since not having one would reduce the effectiveness of the encryption.)Įncryption protects the sensitive data on your phone. If someone doesn’t know the encryption PIN or password, they can’t access your data. It’s the same technology used by a variety of Linux distributions.) When you enter your PIN, password, or pattern on the lock screen, your phone decrypts the data, making it understandable.

(To actually perform the low-level encryption functions, Android uses dm-crypt, which is the standard disk encryption system in the Linux kernel. Encryption stores your phone’s data in an unreadable, seemingly scrambled form.
