Take steps to protect your personal and financial information online

  • Ensure your computer is equipped with sufficient spyware, virus protection, and a firewall to assist in preventing unauthorized access.
  • Download updates and patches for your operating system and software.
  • Browser updates for any browser used on your computer should be completed as they are issued. Add-ons used in connection with your internet browser should be disabled to avoid possible security issues.
  • Rotate/change your username and password regularly – we suggest every 60-90 days.
  • Do not store passwords or usernames on your computer or mobile device as this can be a risk of exposing your personal information.
  • Only shop online at trusted sites – sites that you are familiar with and have the appropriate security measures in place i.e. https:// or the lock symbol found in beginning of the web address bar in your browser.
