Online Banking and Mobile Banking Technical Requirements

System Requirements

The computer you use must meet the following minimum requirements:

  • Standard PC or Mac® with at least 1-GHz processor and 1 GB of RAM.
  • Available browser updates applied for improved security that provide anti-virus and spyware protection.
  • Microsoft® Windows® 7 / 8 / 10 or Mac OS X
    • Note: Microsoft stopped supporting Windows® XP and XP-compatible Internet Explorer (IE) in April 2014, including security updates. XP users who do not upgrade their operating systems should replace IE with Google ChromeTM for an up-to-date, secure Internet browser. If you are currently using Windows XP, TDECU highly recommends you upgrade your operating system due to security vulnerabilities that could impact your financial information and other valuable information.
  • Cable, Digital Subscriber Line (DSL), or Integrated Services for Digital Network (ISDN) Internet connection. (Dial-up connections are not supported.)
    • Note: Satellite connections often have difficulty supporting encrypted, Hypertext Transfer Protocol Secure (HTTPS) applications. Since Online and Mobile Banking are HTTPS-encrypted for the safety of your financial information, some satellite cable connections may exhibit slow responses.

Display Requirements

Desktop and laptop displays can be any height but must support at least a 1300-pixel width. Otherwise, you may need to scroll horizontally to see the entire Online Banking interface.

PDF Reader Requirements

We recommend the most recent version of Adobe® Reader® available for desktop and mobile devices to view online statements and agreements. PDF content on our site requires Adobe® Reader® 6.0 or later. Free Download - You may download Adobe Reader for free.

Fingerprint Login/Touch Authentication Requirements

Fingerprint Login is currently only available for login authentication on eligible Android devices. This is a free feature, pending the following operating system, hardware, and release requirements:

  • Samsung Galaxy S7 or higher
  • Nexus 7 or newer
  • Google Pixel first generation or newer
  • End user registration with Fingerprint at the device level

Touch Authentication is currently only available for login authentication on eligible Apple iOS devices. This is a free feature, pending the following operating system, hardware, and release requirements:

  • iOS 9 or higher
  • iPhone 5S/6/6 Plus or newer
  • Latest generation iPad with Touch ID sensor
  • End user registration with Touch ID at the device level

Note for Android Devices: The Fingerprint Login feature is based on the fingerprint interface that Android introduced with Android M (Marshmallow). Not all Samsung and Nexus devices support Android's fingerprint interface, even though they include the hardware on the device. Therefore, for these affected devices, the Fingerprint Login feature is not supported and Members will not be presented with an option to enable or disable this feature. As new interfaces are provided by Samsung and Nexus device manufacturers, our service partner will work to integrate the Fingerprint Login functionality for use with those devices.

Browser Requirements

For the most secure experience using Online Banking, we recommend that you use the latest version of the supported browsers listed on this page, keep your browser security settings up to date and enable JavaScript. Internet browser support is subject to change with little to no notice and we encourage you to configure your browsers for automatic updates.

In some circumstances, we may need to block certain browsers and software from accessing Online Banking and Mobile Banking due to possible security risks and may not be able to inform you in advance. If you attempt to log in with an unsupported browser, you will be redirected to a website to download a new version of the browser.

    • Note: For the most secure and consistent experience on mobile devices and tablets, use our mobile app instead of your mobile browser. See the Mobile Application Requirements section for more information.

We do not test third-party software (such as browser extensions, plug-ins, non-credit union provided mobile applications, or non-TDECU supported Personal Financial Management (PFM) applications) to determine compatibility with Online Banking or Mobile Banking.
