FAQ: How do I enable TLS 1.2 on ArcGIS Pro?

Question

How do I enable TLS 1.2 on ArcGIS Pro?

Answer

Esri is committed to building and providing strong security for the ArcGIS Platform by using the latest security protocols. We strive to implement the highest industry standards, including Transport Layer Security (TLS), for data integrity and network security.

To meet these standards, Esri is making software updates across the ArcGIS Platform to support TLS 1.2. As part of improving ArcGIS Online security, Esri is planning to require TLS 1.2 connections for ArcGIS Online services. Action is required to ensure continued access to these services.

Note:
See the Product Life Cycle pages on the Esri Support site for the support status of each version of ArcGIS Pro.

The steps to resolve this issue depend on the version of ArcGIS Pro in use:

ArcGIS Pro versions 1.3 – 2.3:

No action is needed to use TLS 1.2. Please note that ArcGIS Pro versions 1.3 - 1.4.1 are retired; Esri recommends upgrading to the latest release.

ArcGIS Pro versions 1.0 – 1.2:

These versions support TLS 1.0, are now retired, and will not be updated. If you continue to run a retired version of ArcGIS Pro, there are two options:

Upgrade to a supported version of ArcGIS Pro - this is the recommended option.
Set the operating system to always enable TLS 1.2. This enables all applications on the system that depend on the Microsoft .NET Framework to use TLS 1.2.
See: How To: Configure Windows to use TLS 1.2 for applications that use the .NET4 Framework

Note:
Consider your situation when deciding which approach to use. Setting the .NET environment to enable TLS 1.2 will not cause problems ArcGIS; however, this may impact other applications by changing their default TLS behavior. Consult a qualified computer systems professional, if necessary.
