To help prevent fraud, when you log in to online banking or the mobile app from a new device you will also need to enter a secure access code that will be sent to you via a phone call or text message. Once that code is entered you can choose to register your device so that future logins don't require this second verification step. For security purposes please do not register public computers.

In order to choose the text message option, or to change the phone number where you receive secure access codes, you may need to update your Secure Access Delivery contact information. You can update your Secure Access Delivery contact information via online banking or the mobile app. If you're not able to login, please call our Member Assistance Center (319) 339-1000 and we can help you update your contact details.
