Apple’s recently published iOS26 operating system required a re-write of our mobile banking application for the Apple device platform. 

The new app version is available in the Apple App Store, but your device may have updated already if automatic updates are enabled.

The app has some new design elements in addition to some new features and functionality.  As such, the first time you log into the new app you will be required to enter your username and password.  Once logged in you can enable and configure multifactor authentication methods (click your username in the upper right and choose Security), enable biometrics (click the “three lines” menu in the upper left and choose Settings), etc.
