clicking login redirects to microsoft login page unless I open private window

Clicking login redirects to Microsoft login page unless I open a private window.

It redirects to https://login.microsoftonline.com. But login in there doesn't work.
I use firefox.

For me the 'federated logon' still pops out when I begin logged-out and click on the "black head" icon on any forum page. I've logged on from the main st.com page, then browsed to the community. I guess this happens to people with Edge browser and email addresses associated with Microsoft.

 

Thanks @Pavel A.  for reporting. I will add this to the ongoing investigation.

Update:

Because of the comment of @Pavel A. I got curious. I discovered the following behavior:

  • yesterday I could not log in, because it forced microsoft login and microsoft login failed, only login in via private window in firefox worked
  • this morning I could log in the normal way
  • after Pavel's comment I tried the following
  • I logged out and could log back in the normal way 
  • then I logged in on answers.microsoft.com with the same email
  • logging out on st and logging back in now fails. It forces the microsoft login. So I suspected it sees I'm logged in to microsoft with the same email
  • I logged out of microsoft. Trying to log in on st fails and forces microsoft login. This is odd to me.
  • I tried to use a private window. but this time logging in failed in the private window too!
  • It does work in Chrome's incognito.

I think like something is stored on the server site, because a new private window should not have retained cookies.

Edit:

after waiting a certain time it does work again...
Edit2:
after a longer wait it fails again. Also sometimes fails in Chrome incognito. Seems very inconsistent.

Hello @Lina_DABASINSKAITE  ,

 

same/similar problem on my PC (on MX-Linux , Chrome up to date); since Fr 27/6/25 probably.

cannot login anymore, just this microsoft nonsense coming, without any working login with email + passwd.

So i didnt login any more....if STM dont want me to login, its ok also.

Here at work (Win, Firefox , not up to date) login still working as before.

I get this with Edge or Firefox, opening a private window in Firefox allowed me to login.

I also had the stated problems of signing in to community.st.com (i.e., getting redirected to Microsoft Live Single-Signon for tenant STMicroelectronics), despite having no problems with signing in or being automatically signed in on other STMicroelectronics SSO-based web properties (e.g., www.st.com , ols.st.com etc.)

I fixed the issue in the following way:

On community.st.com pages, the footer includes a "Manage cookies" link. Clicking on it pops up a onetrust-based "Privacy Preference Center". As I had previously (days ago) declined all cookies in the first-visit cookie banner, in this popup now I was given a "Allow All" button as an action option. After and since clicking this button, I'm able to sign in: i.e. clicking "Sign in to post" no longer brings me to the Microsoft tenant sig-nin page, but to the sign-in page over at my.st.com.

Of course this issue still needs to get resolved from ST's side, as it shall be possible (GDPR) to use community.st.com without consenting to onetrust's privacy-intrusive behavior (which includes sharing data to third-party "advertising partners").

Can you share the "manage cookies" link? In Firefox and Brave the "link" is not clickable. It's just underlined text. The other texts are clickable links.
