Online Banking Security

Click here to see how our Powerful, Multi Security System works!


The access process begins with you typing in your correct User ID and Password.

Then we check the device you are using – whether it’s your computer, mobile phone or tablet. If we don’t recognize the device, we may ask you to complete a Security Challenge to ensure your identity.

We also check geographic indicators. If you’re trying to log in from a new location, we may ask additional questions.


Beginning April 17th 2014 - we will begin phasing out the image and passphrase security feature you currently see when logging in to online banking. This will be replaced with the extended validation certificates (EV) showing below.

The EV certificates will change the URL address bars to green, providing you with visual confirmation that you are on a valid website.


Security you can check:

Before entering your password or answering the Security Challenge, check your browser’s address bar. We’ve added an additional layer of security that shows if you are connected to a safe server. If your browser’s address bar is GREEN, your connection is safe. If it’s not GREEN, stop your log in process and contact us. 

Here's how the GREEN address bar may appear in your browser.

We want you to know your account is safe with us. If you have any questions about the security we use for our online services, feel free to contact us at (517)439-4300.
