Online and mobile banking: better than ever.

On October 23, First Interstate will unveil a new and improved online/mobile banking platform. We’ve taken our customers’ feedback to heart and have developed an easy-to-use system with enhanced features not currently available. Review our Digital Banking Guide for more information.


When you first log in to Personal Online Banking on or after October 23, your username will be the same as your current Access ID. Your password will be reset to the last four digits of your Tax Identification Number—either your Social Security Number or your Employer Identification Number.
