After Browser Login, Pop-Up Prompts to Login with Microsoft Account?

I login to OneDrive via web browser with my work credentials, and I am brought to the default OneDrive page with the "Home" location selected on the left (see photo). When I click "My Files", a pop-up appears prompting me to:

"__Please sign in
__Sign into your Microsoft account to continue.
[Sign In] [Not Now]"

I am already signed in, and if I click [Not Now] I am brought to my files and can access them without issue.

  1. Why am I repeatedly being prompted to Sign In a second time after I login?
  2. What is the purpose of this second login?
  3. How can I stop this pop-up from appearing each time I login to OneDrive?

I'm working on a Mac and I do not have have the OneDrive Application installed, nor do I want it installed. This happens in many browsers: Safari, Google Chrome, Firefox. It also happens on other computers - even Windows PCs.

    Dear JV

    Thank you for contacting the Q&A forum. To better assist you, could you kindly confirm the following:

    1. If you log in using a different browser (one that has not previously been used for Microsoft sign-ins), does the same pop-up appear?
    2. If you use Private/Incognito mode in your current browser, do you experience the same behavior?
    3. In the browser where the issue occurs, are you signed in to multiple Microsoft accounts (for example, both a work/business account and a personal Microsoft account)?

    In the event that the pop-up does not appear in scenarios 1 or 2, we recommend clearing cookies in your current browser. For Safari, you can do this by navigating to: Settings > Privacy > Manage Website Data > Search for microsoft.com and live.com > Select them and click Remove.

    Looking forward to your reply.
