Online Account Opening

Is my online account opening application secure?

Service: Online Account Opening | Updated: April 4th, 2023

Answer:

Yes. First Interstate Bank uses encryption for online security. Encryption technology helps secure information transmission along the Internet by encoding the transmitted data using a mathematical formula to scramble the data. Without a corresponding decoder, the transmission would look like nonsense text and be unusable.
