Microsoft SharePoint Online Validation Loop

[cnx_mk]

Description of the issue:

Sharepoint Online (Office 365) continually asks me to validate my account when accessing documents via Brave.

1. We’ve tested using FireFox, Edge and Chrome, none of which have any issues.
2. We cleared all history, cached cookies and all website data.
3. We tried switching off Brave shield.
4. We use Multi Factor Authentication for Office 365.

Steps to Reproduce (add as many as necessary): 1. 2. 3.

1. Log into your https://.sharepoint.com site
2. Access any team site
3. Access shared documents library
4. Try to open a document

We’ve experienced the problem after both 3 and 4.

Actual Result (gifs and screenshots are welcome!):

Expected result:

Normally we can open a file without being asked to validate over and over and over again.

Reproduces how often:

Every. Single. Time. We. Open. The. Document. Library.

Operating System and Brave Version(See the About Brave page in the main menu):

MAC OSX, Windows 10 Pro, Home, Enterprise.
Brave Version 0.68.139 Chromium: 77.0.3865.90 (Official Build) (64-bit)
