To Our valued Online Banking Customers:
As use of computers in public spaces such as libraries, cyber-cafes, and at work become more common, all Online Banking users should be mindful of the importance of properly ending their banking session prior to leaving the computer, but also that you are utilizing an unsecured wireless connection. We strongly suggest that you limit the types of internet browsing performed over an unsecured internet session, as well as following these log-off procedures to ensure that data remains private and secure.

Proper Log-off procedures:
The correct way to end your online banking session is to click “sign -off” on the navigation bar. If you are within the bill payment section of Online Banking, click “Account Summary” to return to the online banking section and then click “sign-off”. Also, be sure to close any open windows that may have been created within your session. These procedures are of the utmost importance especially when accessing your account information from a public or workplace computer.
