Security Center


A higher level of online security

ONBSecure is our Online Banking authentication system that further protects your confidential account information from phishing. 

How Does ONBSecure Work?

ONBSecure learns and monitors your Online Banking routine – the computers and web browsers you typically use, the time of day you usually bank online, etc. If you break from your normal routine, ONBSecure responds by asking one of the simple, pre-determined security questions that you set up and to which you provide an answer. ONBSecure also asks you one of your pre-determined security questions about once a month, as an additional identity check.

Setting Up ONBSecure

  • Log on to the Online Banking system with your username and password.
  • Select and provide answers to the ONBSecure questions.

Sending Us Secure Messages

Within our Online Banking, we provide an option for sending us messages securely and privately. Once you are logged in to Online Banking, simply choose the Message tab. Messages sent through Online Banking are encrypted, or changed into unrecognizable characters, so that they cannot be read if intercepted by anyone. You should never send us confidential information, such as your account number, by email or through the Email Us form on our web site.
