I see a number of Risky Sign-ins with the code 50173 - Fresh auth token is needed. Have the user re-sign using fresh credentials. And the status is "Failure".
But I noticed the IP address captured is of another country. How to interpret the error code?

If you get an alert from Identity Protection, you can never be 100% sure why it was flagged as risky as Microsoft keeps these methods confidential.
I would suggest you check with the never if he has any clue why this login occurred ( he might be travelling, using roaming data or VPN).
If he doesn't know anything about this login, I would advise you to change his password and expire all his tokens. Even if he has MFA, his account could still be breached.

Thanks for your advice. I have reset the password.
If the status of the code shows "Failure", is that also indicating that the user account has been compromise? Or someone did successfully gain access to the account prior to this?
Or it could be just an attempt? Thanks.

I think is not MFA. This is the failure reason.
I assume someone out there is trying to established the connection. But I wasn't sure whether by "token auth", does it mean somebody has successfully created/login to the account before.
