Encryption

Encryption scrambles your data into unreadable code so only someone with the right key can read it, even if the data is stolen or intercepted.

Encryption: Encryption is the process of turning readable data into scrambled code using a key. Only a person or device holding the correct key can turn it back. It protects files on a phone, messages in transit and passwords stored by websites from being read by thieves.

Modern Android phones encrypt their storage by default. That means a thief who removes the memory cannot read your photos without your screen lock. Websites with the padlock in the address bar also use encryption, so that your login travels in scrambled form across the internet and Wi-Fi network. Encryption also protects chats and payments in transit, which is why public Wi-Fi is far less risky than it used to be.

Encryption is only as good as the key. A weak PIN such as 1234 or your birth year makes it easy to guess. Encryption also does not help when you are tricked into handing over data yourself. Use a strong screen lock, keep devices updated and be careful where you type your passwords. Apps that skip encryption are a red flag, so avoid sending personal details through them.

Tips

• Set a long PIN or password, since it guards the key that encrypts your phone.
• Check for the padlock and the exact website name before logging in.
• Keep backups encrypted or protected with a strong password.
