RCU Online banking uses a variety of methods to verify your identity, which ensures your security when banking online. Part of this process involves the use of challenge (security) questions, which the system will ask you when it senses any differences in how your account is accessed, such as logging in from a different computer. You do not need to put sensitive personal information online. The answers you provide just need to be ones that you will be able to recall.
You may also change your security questions or the answers to your questions if you wish.
