First Time Login Setup

Welcome to First Interstate Bank. For your convenience, your Idaho Independent Bank (IIBK) and/or Community 1st Bank (CMYF) accounts have been automatically transitioned to First Interstate and are now accessible through First Interstate’s Online Banking platform.

Before you begin, test your browser to ensure it is compatible with Online Banking.

If you have accounts at both institutions, either login ID will work.
