TLS 1.0 Security Update & Changes

July 09, 2018

On July 16 , 2018, WECU will be officially retiring TLS 1.0 security protocol support on all of our services in order to align with industry best practices and ensure that your data continues to be highly secure.

TLS stands for “Transport Layer Security.” It is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network.

As of July 16, 2018, we will disable the TLS 1.0 encryption protocol, which may prevent you from using some or all of your online and mobile banking functionality. To prevent disruption, you may need to upgrade your browser to a version that supports TLS 1.1 or higher. Outside of the browser upgrade, this change will not affect you in any other way.

Secure Browsers:

The following browsers support using TLS 1.1 or higher. If you are NOT using these browsers/versions, you may not be able to access some or all of our online services.

  • Microsoft Internet Explorer (IE): Version 11 and higher
  • Microsoft Edge: All versions
  • Mozilla Firefox: Version 27 and higher
  • Google Chrome: Version 38 and higher
  • Apple Safari Desktop: Versions 7 and higher for OS X 10.9 (Mavericks) and higher (7)
  • Apple Safari Mobile: Versions 5 and higher for iOS 5 and higher
  • Google Android OS: Android 5.0 and higher

How to test your if your browser is compatible

SSL Labs provides a compatibility test that can be used to verify web browsers support TLS 1.1 or later:


If the Protocol Support box on the validation site says, “Your user agent has good protocol support.”, you are all set – no action is required.

If you have any questions or concerns, please reach out to our Contact Center at 800-525-8703 with any questions or concerns. We aim for this process to be as smooth and simple as possible. Our primary goal is to ensure member data remains safe and secure.
