IoT Hub deprecation of support for TLS 1.0/1.1 is postponed

Published date: 14 April, 2020

The deadline for IoT Hub deprecation of support for transport layer security (TLS) 1.0/1.1 is postponed indefinitely. IoT Hub will continue to support TLS 1.0/1.1 until further notice to ensure compatibility with existing applications and devices.

It was previously announced that IoT Hub would deprecate support for TLS 1.0/1.1 on July 1, 2020. After reviewing customer feedback, we're postponing the deadline for migration indefinitely. However, all customers should migrate to TLS 1.2 as soon as possible. To learn more about this policy, which covers all of Azure, read Preparing for TLS 1.2 in Microsoft Azure.

Correction—April 14, 2020

Our previous announcement misstated that Device Provisioning Service would deprecate support for TLS 1.0/1.1 as well. Device Provisioning Service doesn't support TLS 1.0/1.1—it supports TLS 1.2 only—so the deprecation notice was unnecessary.
