Technical Requirements

Digital Banking

NOTE: Effective October 22, 2020, we will discontinue support of Android Operating System (OS) versions 5.x and 6.x due to the low usage rate, the increased costs of maintenance, and security considerations of older versions of the Android OS.

What this means to you:

  • Issues that you may experience using the TDECU Digital Banking app on Android devices running OS versions 5.x and 6.x will no longer be supported.

  • Older versions of the TDECU Digital Banking app may continue to function; however, Members will need to make sure to turn off auto-update for the TDECU Digital Banking app. This action will allow Members to remain on older app versions. Instructions on how to turn auto-updating off for the TDECU Digital Banking app can be viewed here.

  • Members that wish to continue using an Android device with an unsupported Android OS will no longer receive updates to the TDECU Digital Banking app and features and functionality may no longer work as updated versions of the app are released in the future.

Digital Banking Browser Support

Is your internet browser up-to-date? Keeping your internet browser updated regularly helps improve online security!

NOTE: As online fraud continues to evolve, browsers have been updated to become more secure. In fact, Microsoft recently announced it will stop supporting Internet Explorer 11 in the near future in favor of new, more secure browsers, like Microsoft Edge.

In accordance with best practices, after October 6, 2020, TDECU Digital Banking no longer allowed Members to log in using Microsoft Internet Explorer 11.

Download or update one of the following supported browsers to improve your secure digital banking experience.


Google Chrome

Download Chrome

Microsoft Edge

Update Edge

Mozilla Firefox

Download Firefox

Browser Requirements

For the most secure experience using Digital 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 Digital 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 Digital Banking.

Some minimally supported browsers, listed below may show minor behavioral or cosmetic differences in Digital Banking, but generally, support the Digital Banking features and functionality.

Supported browsers Windows® 10
Google ChromeTM (Current version plus the previous two versions are supported) Free Download
Microsoft Edge (Current version plus the previous two versions are supported) Free Download
Microsoft Internet Explorer 11.x Unsupported as of 10/06/2020
Mozilla® Firefox® (Current version plus the previous two versions are supported) Free Download

Note the following details about the PC Browser Compatibility table:

  • Digital Banking is not compatible with Safari® on Microsoft Windows®, as Apple discontinued development of security patches for Microsoft Windows.
  • As of October 6, 2020 support for Microsoft Internet Explorer has ended and members will not be able to access Digital Banking utilizing the Microsoft Internet Explorer.
  • Digital Banking is compatible with Safari® on Mac®OS X 10.10 and later, as shown in the next table.

If you need technical assistance downloading your browser, contact your Internet Service Provider (ISP) for assistance.

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.
  • Microsoft® Windows® 10 or Mac OS X 10.10
  • Available browser updates applied for improved security that provide anti-virus and spyware protection.
  • An Internet Connection with a minimum of 1 Mbps download speed.
    • Note: Satellite connections often have difficulty supporting encrypted, Hypertext Transfer Protocol Secure (HTTPS) applications. Since Digital Banking is 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 we recommend at least a 1300-pixel width. Most Members will be able to view most pages without scrolling; however, on occasion you may need to scroll horizontally to see the entire Digital Banking interface.

PDF Reader Requirements

We recommend the most recent version of Adobe® Reader® available for desktop and mobile devices to view online documents. If you choose to use a third-party PDF application, we cannot guarantee documents will appear as intended. PDF content on our site requires Adobe® Reader® 6.0 or later.

Download Adobe Reader – Free

Biometrics Requirements

Fingerprint Login is a free feature currently only available for login authentication on eligible Android devices. To use this feature you must meet the following operating system, hardware, and release requirements:

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

Touch ID and Face ID are only available for login authentication on supported Apple iOS devices and requires end-user registration of the feature at the device level.

  • iOS 10 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.

Mobile Application Requirements

This section describes the operating systems, connection types, and camera resolutions that are compatible with the TDECU Digital Banking app that Members can download from the Apple Store (for iOS devices) or Google Play (for Android devices).

  • TDECU Digital Banking functions best when GPS or a native mapping app (also called Location Services) is enabled.
