Step 1: Enable encryption on the device
Mobile devices often have built-in encryption features to protect data. Enable encryption to ensure that even if the device falls into the wrong hands, the data will be unreadable without the proper decryption key. \text{Encryption: } Enc(data) = decryption \ key \Rightarrow readable \ data
Step 2: Use two-factor authentication
Two-factor authentication adds an extra layer of security to your device by requiring two methods of verification to access the data. This usually involves something you know (a password or PIN) and something you have (a physical token or your mobile device). \text{Two-factor authentication: } Authenticate(user, password, token) \rightarrow access
