You will notice minor changes to the login process. After you have successfully logged in, the format will be slightly different. All previous functions are still available. If you have any questions or need additional assistance, please contact our main office during normal business hours at 262-784-4400 (Monday-Friday, 8:30am-5pm) and ask for Retail Online Banking.


Site Authentication Security

An EV certificate will change our Online Banking website URL address bar on our password page to GREEN, providing our customers with visual confirmation that they are on our VALID website and NOT a fraudulent, spoofed website only made to look like our website.

Keeping your Accounts Safe

There are a number of actions you can take to keep your account information safe and secure:

  • Great Midwest Bank will never contact you with an unsolicited phone call or email to ask for your personal or account information.  Those are details we already have on file.  Fraudsters have been known to “spoof” a bank phone number to give the appearance of a call from the bank.  If you are questioning the validity of a call, hang up and call us at the number below!
  • Refrain from using free Wi-Fi in restaurants, hotels and other public spaces for online and mobile banking.  You are better off using the data connection through your phone’s service provider.
  • Be sure that your mobile banking app is up to date with the latest security patches.
  • Consider changing your banking password every three months.  You can do so after logging in to online banking, under Profile.

At Great Midwest Bank, we’re committed to keeping your personal financial data safe and secure.  We welcome your feedback on our security measures, and encourage you to contact us with any questions or concerns at (888) 485-4400 or via email.
