The Seamless SharePoint Add-In requires an authentication using the Microsoft Identity platform. The Microsoft Authentication Library (MSAL) enables developers to acquire tokens from the Microsoft identity platform in order to authenticate users and access secured web APIs.
This authentication requires that you
- allow pop-ups from https.//yourtenant.sharepoint.com
- allow cross-site tracking
If your browser security settings prevent pop-ups and/or the our 3rd party cookies, the sign-in will fail and a corresponding message with a button indicating "Click here to proceed" will be displayed. Additionally, your browser will notify you, that pop-ups and 3rd party cookies are blocked.

Allow cross-site tracking
Cross-site tracking is similar to 3rd party cookies in other browsers. To use Seamless without returning authentication, we recommend allowing cross-site tracking. In your browser settings, deactivate the "Prevent cross-site tracking" option.
