*No matter what kind of mobile banking method you use, reduce fraud and protect your money by following a few common-sense precautions:

  • Set the phone to require a password to power on the device or unlock it.
  • Whether you’re using the mobile web or a mobile app, don’t let it automatically log you in to your bank account. Otherwise, if your phone is lost or stolen, someone will have free access to your money.
  • Avoid sharing your password, account number, PIN, answers to secret questions or other such information. Don’t save this information anywhere on your handset.
  • Immediately tell your bank or mobile operator if you lose your phone.


Kasasa Protect is a great tool for monitoring and protecting your identity. For more information visit our Kasasa Protect page.

We need your help to keep your OakStar Bank account information secure. We will never contact you either by phone or by email and ask for:

  • Your account information

Commercial customers are encouraged to perform a risk assessment and controls evaluation on all online banking access points on a regular basis. 

  • Never click on emails notifying you of "compromised" security. These emails are attempts to steal your identity.
  • Never answer personal questions over the phone from an incoming (unsolicited) call.
  • Never give access to your personal computer to someone who has called you to tell you your computer is compromised. These are not legitimate calls.
  • Always shred documents containing personal information.
