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® Vista Service Pack (SP) 2 or 3, Windows® 7 / 8 / 10
- 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.
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.
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.
