You may have received notices from various companies saying they're stopping support for TLS 1.0.

Here's what that means: Transport Layer Security (TLS) is a security system that protects your Internet communications by preventing hackers from reading your messages. TLS 1.0 was the first version; it was effective at the time of its release. However, as hackers improved their techniques and computers became more powerful, TLS 1.0 became less secure. Consequently, newer versions, such as TLS 1.1 and 1.2, were developed to provide stronger security.

Many companies kept using TLS 1.0 because older computers can't use the newer versions. But now TLS 1.0 is too easy to hack, so most companies are stopping its use.

If you're using Windows XP or Vista, your computer won't be able to connect to these companies unless you upgrade to a newer Windows version. If you're using Windows 7 or newer, you should be fine as long as you have a recent version of TLS turned on. Windows 8 and newer usually have this on automatically. For Windows 7, you might need to turn it on yourself. Here's how to make sure it's on:
