Frequently asked questions
What is the TLS 1.0 protocol?
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. TLS ensures that a connection to a remote endpoint is the intended endpoint through encryption and endpoint identity verification. The versions of TLS, to date, are TLS 1.0, 1.1 and 1.2.
What is the reason for this change?
TLS aims to provide privacy and data integrity between two communicating applications. TLS 1.1 and above provide significantly higher security controls than TLS 1.0. Protecting your data is of the utmost importance for us, and this disablement will allow us to better ensure the security of your data. Our goal is to make this process as seamless as possible while maintaining the highest security standards.
I use an Android device to access my accounts. Why can't I access my mobile banking application?
Members operating on Android version KitKat (4.4) and lower, which includes about 20% of the U.S. population according to current usage patterns, may be impacted by the disablement of TLS 1.0 as these versions do not support TLS 1.1 and 1.2. Upgrading to Lollipop (5.0) or higher will fix this issue and support TLS 1.1 and 1.2 or you may download the latest Google Chrome or Firefox for Android applications from the Google Play Store.
