Microsoft Entra flagged sign-ins

As an IT admin, you want to resolve sign-in issues as soon as possible to unblock your users. Due to the amount of available data in the sign-in log, locating the right information can be a challenge.

This article gives you an overview of the flagged sign-ins feature that can significantly improve the time it takes to resolve user sign-in problems by making the related problems easier to find.

What are flagged sign-ins?

Microsoft Entra sign-in events are critical to understanding what happened with user sign-ins and the authentication configurations in your tenant. However, Microsoft Entra ID processes over 8 billion authentications a day, which can result in so many sign-in events that admins might find it difficult to find the ones that matter.

The flagged sign-ins feature is intended to improve the signal to noise ratio for user sign-ins that require your support. The feature allows users to raise awareness about sign-in errors they need help with. Admins and help desk workers also benefit from finding the right events more efficiently. Flagged sign-in events contain the same information as other sign-in events but they also indicate that a user flagged the event for review.

You can use flagged sign-ins to:

  • Empower users to proactively indicate which sign-in errors require IT admin support.

  • Simplify the process of locating sign-in errors.

  • Enable help desk personnel to find sign-in errors without the end user having to do anything other than flag the event.

How it works

When users see a sign-in error, they can choose to enable flagging. For the next 20 minutes, any sign-in event from that user, on the same browser and client device or computer, displays Flagged for Review: Yes in the sign-in logs. After 20 minutes, the flagging automatically turns off.

User: How to flag an error

  1. The user receives an error during sign-in.

  2. The user selects View details in the error page.

  3. In the Troubleshooting details section, the user selects Enable flagging.

    • The text changes to Disable Flagging and flagging is now enabled.
    • The user must use the same browser and client or the events aren't flagged.

  4. Open a new browser window (in the same browser application) and attempt the same sign-in that failed.

If the sign-in error is reproduced, the flagged diagnostics are sent to the sign-in logs.

Admin: Find flagged events in reports

The sign-in logs might take several minutes for the flagged sign-in events to appear.

  1. Sign in to the Microsoft Entra admin center as at least a Reports Reader.

  2. Browse to Identity > Monitoring & health > Sign-in logs.

  3. Open the Add filters menu and select Flagged for review. All flagged events are shown.

  5. Select the event to review what happened.

Admin or Developer: Find flagged events using Microsoft Graph

You can find flagged sign-ins using the Microsoft Graph API. For more information, see the signIn resource type Microsoft Graph documentation.

Flagged Sign-ins query for specific user by UPN (for example: user@contoso.com):

  • https://graph.microsoft.com/beta/auditLogs/signIns?&$filter=flaggedforReview eq true and userPrincipalname eq 'user@contoso.com'

Flagged Sign-ins query for specific user and date greater than:

  • https://graph.microsoft.com/beta/auditLogs/signIns?&$filter=flaggedforReview eq true and createdDateTime ge 2021-10-01 and userPrincipalname eq 'user@contoso.com'

Who can create flagged sign-ins?

Any user signing into Microsoft Entra ID can flag sign-ins for review, including member and guest users.

Who can review flagged sign-ins?

Reviewing flagged sign-in events requires permissions to read the sign-in report events in the Microsoft Entra admin center. For more information, see How to access activity logs.

What you should know

While the names are similar, flagged sign-ins and risky sign-ins are different capabilities:

  • Flagged sign-ins are sign-in error events users are asking assistance on.
  • A risky sign-in is a functionality of Microsoft Entra ID Protection. For more information, see What is Microsoft Entra ID Protection.
