Question

Chrome Asking for MS Authentication (MFA) Every Time It Is Launched

Dieter Tontsch (GMail) 972

Hello,

one of our employees got a problem with MS authentication (in this case it is MFA too) and the Chrome browser. Every time she launches Chrome, our SharePoint is her start page, she instantly gets prompted to login. She can login, no problem, but if 5 minutes later, after she has closed chrome and opens it again, the same thing.

It only happens with Chrome, Edge or Firefox for instance, do behave normally. Any idea what it can be? We already have cleard cache, cookies etc... no difference.

Someone in this post points to a problem with Chrome not beeing the default browser? I don't know yet what her def. browser is, I might check on that.

I dealt with this yesterday for a staff member. He was using a Mac and was getting the prompt for a keychain password. Once we resolved that he then tried logging into Office. He not only kept getting prompted but also was getting an error from the provided numbers to put into the MS Authenticator saying they were invalid. Double checked the time on both devices, Company portal was synced, all apps were up to date and no policies have changed that would have caused that.

Lone behold we switched to Edge and it was working no problem. At this time we believe the culprit to be a Chrome setting that doesn't like MS Authenticator for whatever reason.

I am having the same problem, works in edge but in chrome she authenticates and it just loops non stop. She is using the outlook app on her phone to authentication it says it works but then asks her to do it again. Let me know if you find a fix!

So she's trying to use Outlook on her phone? Or using her phone to authenticate to Outlook on her computer? If that's the case and the users are enrolled in Entra, try opening the company portal app and logging in if not already. Then try re-syncing. It should be a setting in Company portal.

Also reach out to your IT Admin to reset the authentication methods if that fails.
