Does Lucid support Nested App Authentication (NAA) for Microsoft integrations?

Hi ​@SheldonSven 

Lucidchart's Office Add-ins for Excel and PowerPoint support authentication via Azure Active Directory (Azure AD) using standard OAuth 2.0 and NAA is not yet an available option.

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards

Hi ​@SheldonSven, thank you for posting in the Lucid Community!

As ​@Humas1985 mentioned, unfortunately, this isn’t currently supported in Lucid, but we’re very interested in your feedback and committed to continually improving our products.

If you’re willing to share, we’d love to hear more details about your use case or what you’d like to see in this experience within this thread. I’ve also converted this post to an idea so that it’s visible to others within the Product Feedback section of the community - from here, they can upvote it and add details of their own.

Finally, for more information on how Lucid manages feedback via this community, take a look at this post:

LucidChart, please make this available as soon as possible. Microsoft has enforced the use of Nested App Authentication for all Microsoft Integrated Apps as of Jun 28, 2025.

We are currently unable to use the Lucid Diagrams add-ins for Office365 because Nested App Auth is not available for these integrations.

Hi ​@ThomasD2, thank you for taking the time to upvote this post and share your feedback here. I certainly see how this is important and I’ve raised this with our product and developer teams.
