Autodesk Identity Services is moving to Transport Layer Security (TLS) 1.2 and will no longer support TLS 1.0 and TLS 1.1 on August 3, 2019.


Transport Layer Security (TLS) 1.0/1.1 is vulnerable to man-in-the-middle (MITM) attack that can compromise data exchanges. This applies to  single-user subscribers using the software versions listed below; customers using software or versions not listed and customers using perpetual or multi-user (network) licenses will not be affected. This also impacts some cloud-connected features of products such as Revit, Dynamo Studio, etc.


Single user subscribers are impacted with a selection of Autodesk software used on Windows, Mac, and Linux versions 2014, 2015, 2016 and/or 2017.

For products such as Revit, all versions (2014-2020) are potentially impacted, depending on the cloud-connected features used.


To align with industry best practices for security and data integrity, Autodesk Identity Services will move to Transport Layer Security (TLS) 1.2 and stop supporting TLS 1.0 and TLS 1.1 on August 3, 2019. 

The best solution to avoid connectivity issues is to download and install a newer version of your software through Autodesk Account or our Autodesk Virtual Agent (AVA).

We have been developing patches to install on on top of products to prevent (or resolve) this issue as part of Autodesk’s ongoing efforts to provide the best security possible to our customers. Subscribers using the software versions listed below will need to download the appropriate License & Identity patch by August 3, 2019. These patches will support TLS 1.2 and above. For customers using Revit cloud-connected features, Revit Cloud Worksharing, and Cloud Models for Revit, additional updates may be necessary.

Failing to apply these patches may result in interrupted software access and connectivity. Please review the table below carefully to understand the impact on the product you use.

Most Autodesk software is affected by this update, but not all versions are. If you’re an Autodesk user, please have a look at this page to see if you are affected: Transport Layer Security (TLS): Updates Required to Maintain Software Access.
