This includes passwords, bank account or credit card numbers, etc.. Confidential information is more likely to be lost or stolen than a computer. If you do choose to store such information on your device, make sure you use an application that encrypts the information, and choose a strong password.

Apply application and operating system updates when they are released. Uninstall unused applications.

You can also sync your device with online back up services. Be sure you understand what information is synced automatically and what information has to be backed up manually, and plan accordingly.

Configure the device to require the password to be entered after a certain period of inactivity (e.g., 5 minutes). Some devices also offer a feature that will erase the information on the device if someone makes repeated attempts to unlock it using the wrong password, but if you choose to enable this feature, make sure you have backups!

Even if you don’t have a smartphone with Internet capabilities, it’s possible to get important information, or even new passwords and access codes, “texted” to your cell. Delete text messages that contain sensitive information.

You should also check online reviews to get a sense of the developer’s credibility. Some apps can host malware that will expose your sensitive information.

When using Wi-Fi, make sure you’re connecting to a known and trusted network.
