Security Tips


Tri-Valley Bank values your personal and confidential information and has taken every measure to ensure that it is protected. However, it is critical that you are aware that the security and integrity of Online Banking (OLB) also depends on your own computer system being adequately protected from both internal and external threats. Tri-Valley Bank strongly recommends that you assess the security of your computer system. You should verify that your system is adequately firewalled and runs a daily comprehensive up-to-date security protection package. This package should include protection against the latest viruses, adware, malware or other computer infections that could enable cyber criminals the ability to access to your personal information.


  • Dedicate and limit the number of computers used to complete online banking transactions; public or unsecured computers should never be used for online banking.
  • We strongly recommend internet browsing or email exchange is from dedicated computers; be sure to register dedicated computer(s) during your initial log-in to OLB.
  • Never leave a computer unattended while using OLB, and never conduct banking transactions while multiple browsers are open on your computer.
  • Passwords should be changed on a periodic basis, should never be shared, and should not be written down nor stored in an unsecure manner.
  • Create a strong password that is at least eight characters long; does not contain your user name, real name, or company name; and includes uppercase letters, lowercase letters, numbers, and special characters.
  • Protect your answers to security questions. Select questions and provide answers that are easy for you to remember, but hard for anyone else to guess. Do not write down your security questions or answers or share them with anyone. If you have selected security questions on other websites, avoid using the same questions to protect your Tri-Valley Bank online account. Please note that we will never ask you to provide answers to your security questions via email.
  • Confirm at each log-in the date and time of your last log-in. This is located on the OLB welcome page in Eastern Time. This section also displays the last failed log in date; if these dates do not match your records, contact the bank as soon as possible.
  • Review and verify all account activity on a daily basis. Be sure to report any suspicious activity immediately.
  • Install a dedicated, actively managed firewall, especially if using a broadband or dedicated connection to the internet, such as DSL or cable. A firewall limits the potential for unauthorized access to the network and computers.
  • Keep virus and spyware detection software up to date. Free software may not provide protection against the latest threats compared with an industry standard product.
  • Check browser settings and select, at minimum, a medium level of security.
  • Clear the browser cache before starting an online banking session in order to eliminate copies of web pages that have been stored on the hard drive.
  • Be suspicious of emails alleging to be from a financial institution, government department, or other agency requesting account information, account verification, or banking access credentials such as usernames, passwords, PIN codes, etc. Never respond to these emails or click on hyperlinks embedded with-in them.
