As Microsoft is removing support for legacy authentication, and webcon is still using base login/password for SharePoint.
Is Webcon planning to implement connecting through application? There is SharePoint via REST, but I'm saying about SharePoint Site Collection connections - these will stop working very soon.

Hi Patryk,
Yes, we're working to address this issue. We’ll replace the current SharePoint Online username/password authentication with OAuth based on App Registration (Client ID / Client Secret), so Site Collection connections should also be covered.
Cheers

Hi Dawid,
could you please share the date a new version will be release which covers SharePoint auth change? For my case it's about 2025.

We're also eagerly awaiting this fix. The old login method is no longer available in several of my tenants.

The change log of release 2026.1.6.198 from 2026-04-21 states that the alternative is now available:

Quote:
Added the ability to configure a SharePoint Online connection in the SharePoint
Site Collection settings window using OAuth 2.0 authentication (the
Credentials field). Configuring this authentication method requires specifying the
tenant identifier (the Tenant ID field) and client identifier (the Client ID field),
uploading a certificate from disk (the Certificate field), and then providing its
password (the Certificate password field)
While there's also a release for 2025 with the same date, I don't find anything similar:

There's also a new article describing it:
