Running into performance issues with digital banking? Check here to make sure we support your current browser and operating system (OS) versions. Plus, running the latest versions will improve your security while online.

Digital Banking Browser Support

Not sure if your internet browser is up to date? Check here to see if you are running the latest version. Remember that keeping your internet browser updated helps improve your online security.

As online fraud continues to evolve, browsers continue to be updated to become more secure. In fact, Microsoft announced it stopped supporting Internet Explorer 11 in favor of new, more secure browsers, like Microsoft Edge.

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

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

Browser requirements and compatibility

To achieve the most secure experience using digital banking, we recommend:

Using the latest version of the supported browsers listed on this page
Keep your browser security settings up to date
Enable JavaScript

For the most secure and consistent experience on mobile devices and tablets, please download our mobile app instead of using your mobile browser. Please see the Mobile Application Requirements section for more information.

Internet browser support is subject to change with little to no notice. We encourage configuring your browsers to automatically update.

If you attempt to log in with an unsupported browser, you will be redirected to a website to download a new version of your browser.

Under certain circumstances, we may need to block certain browsers and software from accessing TDECU Digital Banking due to possible security risks. If this happens, we may not have time to inform you in advance.

Some minimally supported browsers may show minor behavioral or cosmetic differences in digital banking.
