To provide the best-in-class encryption to our customers, Microsoft plans to discontinue the support for Transport Layer Security (TLS) versions 1.0 and 1.1 in the Power BI service as of June 2020.
We understand that the security of your data is important, and we’re committed to transparency about changes that may affect your use of the TLS service.
The Microsoft TLS 1.0 implementation has no known security vulnerabilities. But because of the potential for future protocol downgrade attacks and other TLS vulnerabilities, we are discontinuing support for TLS 1.0 and 1.1.
For information about how to remove TLS 1.0 and 1.1 dependencies, see the whitepaper Solving the TLS 1.0 problem.
As of June 2020, Power BI will begin deprecating TLS 1.0 and 1.1 in worldwide environments for commercial customers and in GCC environments for GCC customers. This means that starting in June 2020, any commercial and GCC clients, devices or services that connect to Power BI by using TLS 1.0 and 1.1 will not succeed.
We recommend that all client-server and browser-server combinations use TLS 1.2 (or a later version) to maintain connection to the Power BI service. You might have to update certain client-server and browser-server combinations, and this can include mobile clients and data connectors used for dataset refreshes.
The following clients are known to be unable to use TLS 1.2. Update these clients to ensure uninterrupted access to the service.
- Android 4.3 and earlier versions
- Firefox version 5.0 and earlier versions
- Internet Explorer 8-10 on Windows 7 and earlier versions
- Internet Explorer 10 on Windows Phone 8
- Safari 6.0.4/OS X10.8.4 and earlier versions
