Online Banking Security

Browser and Device Requirements 

We take your security very seriously. That's why Banner Online and Mobile Banking services require that you use a supported device and browser to access your finances. Current requirements for Banner Online Banking, Banner Mobile Banking, Bill Pay, and Remote Deposit are detailed below.  

If you have questions or need assistance updating your browser, please contact us during business hours at 800-272-9933 or*.

Web browsers and operating systems are a key component to keeping your information secure. As online fraud and theft evolves, the companies that provide Web browsers and operating systems, continually release patches to help keep you one step ahead of the fraudsters. It is vital that individual users, like you, routinely apply those system upgrades to keep the information you access from your smartphone, tablet and computer safe.

  • Always use a current Web browser and operating system when you access online banking. 
  • Never jailbreak or root your mobile device or use a jailbroken or rooted device to access your financial information.
  • Monitor your account frequently and set up security alerts so you are notified immediately if suspicious activity occurs.
  • Enable biometric authentication, such as touch ID or Face ID, on the mobile device you use to access online banking can help prevent unauthorized access to your accounts.

Additional information about security alerts


What should I do if I receive a security alert I was not expecting?

If you receive a security alert that you were not expecting, start by logging into your online banking to learn more. You can review all security alerts in the secure message center and determine what date and time the alert generated. In some cases, like a transaction alert, you can review your transactions by selecting the Activity Center, located under Transactions in your online banking. In some cases, you may determine that you need to set a new user id or password, which you can do from within online or mobile banking.


Can I turn security alerts on or off?

Some security alerts are on by default and can be turned off. Other alerts are set to 'always on' and cannot be changed - these are usually alerts where it's important that you know about changes, like a change to your User ID. There are also some alerts that are off by default but you can turn them on for added protection. To see all available security alerts or make changes, log in to your online banking and go to Settings, then select Alerts.


How can I protect my account?

The best way to protect yourself is to use different user names and passwords for every online account and to make sure your passwords are strong. Passwords should be at least 14 characters long and use a combination of lowercase and capital letters, numbers and special characters like exclamation points and ampersands and do not contain easily discoverable information like your name or birthday.

  • An example of a strong password: C!im6^ngTr3e 
  • An example of a weak password: Bunny!23

The above examples are for inspiration only - for your security, we recommend that you create your own password that is different from the examples.

To change your User ID and password in Banner Online Banking, sign in and select Settings, then go to Security Preferences. 

We also strongly recommend that you have current anti-virus and anti-malware software on your devices you use to log into online banking and that it is up-to-date.

Secure Access Code

What is a Secure Access Code?
A Secure Access Code is a security feature that allows you to register the computer you are using for "one-time" or "future" use.

Why do I need a Secure Access Code?
Registering your computer is another layer of security to ensure your online banking account cannot be accessed by an unregistered computer – even if your Login ID and Password are accidentally or unintentionally compromised.

How does the Secure Access Code work?
When you log in from an unrecognized computer or mobile device, we will send you a single-use Secure Access Code. The code will be delivered to you using secure contact information that we have on file for your accounts. You can choose to have your Secure Access Code delivered via text message, phone call or e-mail, depending on what contact information we have on file for you. Once you receive the temporary Secure Access Code from Banner, enter it in the space provided within login.

When you use a private device that you will frequently use to access online banking, you can “register the device”, which will allow us to recognize the device and browser you’re using. Once you have registered your device, you will not be prompted for a Secure Access Code with future logins. However, if the computer you use is public or one which you do not regularly use, we recommend for your security that you “do not register” the device.

I didn’t receive my Secure Access Code or my contact information is outdated.
Please call us at 800-272-9933 during business hours so we may assist you.

I have registered my device, but online banking prompts for another Secure Access Code. Why?
There are several reasons this may happen. Most commonly this occurs when your browser settings are set up to delete cookies, or your browser cookie for online banking has been deleted since your last login. This can also happen if you are logging in with a different browser on the same registered device. You may have a program on your device that automatically deletes the cookie and that feature would need to be turned off or configured to accept and retain cookies from Banner Bank.

How do I remove the registration from a device?
You can remove the registration of a device or browser by deleting your cookies, or only the cookie related to online banking. and Banner Online Banking Use Cookies


What is a cookie?

A computer cookie is a small text file placed on your computer by a web site that you visited. A cookie is the term given to describe a type of message that is given to your computer’s web browser by a web site you are visiting. The main purpose of a cookie is to identify who you are and possibly prepare customized Web pages or to save site login information for you. Cookies also help tailor your experience when you visit websites.


What does a cookie store?

For the most part a cookie will contain a string of text that contains information about the browser. To work, a cookie does not need to know where you are from, it only needs to “remember” your browser. Some Web sites do use cookies to store more personal information about you. However, this can be done only if you yourself have provided the Web site with that personal information. Legitimate Web sites will encrypt this personal information stored in the cookie to prevent unauthorized usage by another party with access to your cookie folder.


Cookies have six parameters that can be passed to them:


  • The name of the cookie
  • The value of the cookie
  • The expiration date of the cookie
  • The path the cookie is valid for - this sets the URL (address) path the cookie is valid in.
  • The domain(website) the cookie is valid for
  • The need for a secure connection


Are cookies malicious?

No, cookies are not malware. They are not a software program. Cookies normally do not compromise security, but there is a growing trend of malicious cookies. These types of cookies can be used to store and track your activity online. Cookies that watch your online activity are called malicious or tracking cookies. These are the bad cookies to watch for, because they track you and your surfing habits, over time, to build a profile of your interests. Once that profile contains enough information there is a good chance that your information can be sold to an advertising company who then uses this profile information to target you with interest specific adverts. Many antivirus programs today will flag suspicious spyware or adware cookies when scanning your system for viruses. Banner only uses cookies that help tailor your experience on the website.
