Beginning October 7^th, 2024 COREBANK online banking users should expect a change when logging into their online account(s). We are introducing OOBA, or Out Of Band Authentication. OOBA provides an additional layer of security that safeguards the login or certain online banking transactions. It requires a user to go “out-of-band” or out of the Online Banking system and onto a separate system – phone call or text – to validate a login/transaction before it can be completed. For more information, please call Waynoka office: (580) 824-5451 OKC office: (405) 605-2458
