We recognize that our members have a variety of operating systems and web browsers from which to choose, and we want our members to have the best possible experience on the web when using our online banking system. However, we also recognize that it is nearly impossible to support all operating systems and web browsers. You are welcome to continue using an operating system or web browser that we do not officially support. However, STCU will be limited in our ability to support your use and we'll sometimes be unable to guarantee resolutions if you encounter unexpected behavior. We apologize for any inconvenience this may cause.
