Password-protect your smartphone: Always lock your phone when it’s not in use, set it to automatically lock after being idle for a set amount of time. Set your phone to use a longer and stronger password than the default 4-digit unlock code if this option is available on your phone. For even better security, set your phone to erase all data after 10 bad password attempts.
Clear data from your smartphone frequently
Delete text messages from financial institutions, especially before sharing, discarding, or selling your phone. If you visit banking websites using your phone, delete the cookies and cache regularly. Better yet, use dedicated apps for online banking.
Always download apps from reputable sources
Criminals try to lure people into signing up for mobile banking using fake apps and/or websites.
Always visit your direct mobile banking site to verify the sources of your online banking applications. If you’re considering adding an app to your mobile device, review the app’s permissions so you understand what the app is capable of doing before you decide to download it.
Remove personal information before replacing your smartphone.
Don’t rely on carriers, recycling firms or phone deposit banks to “clean” your phone before disposal or resale to third parties. Follow your phone manufacturer’s instructions to remove all personal information from your phone before decommissioning it.
