Name: Export Microsoft 365 Sign-in Failure Report Using PowerShell
|
|||
|
|
Version: 1.0
|
|||
|
|
Website: o365reports.com
|
|||
|
|
|
|||
|
|
~~~~~~~~~~~~~~~~~~
|
|||
|
|
Script Highlights:
|
|||
|
|
~~~~~~~~~~~~~~~~~~
|
|||
|
|
|
|||
|
|
1. The script automatically verifies and installs the Microsoft Graph PowerShell SDK module (if not installed already) upon your confirmation.
|
|||
|
|
2. Generates a report that retrieves all failed interactive sign-in attempts by default.
|
|||
|
|
3. Enables filtering of failed attempts from the following sign-in types.
|
|||
|
|
-> Non-interactive user sign-ins
|
|||
|
|
-> Service principal sign-ins
|
|||
|
|
-> Managed identity sign-ins
|
|||
|
|
-> All type of sign-in failure events
|
|||
|
|
4. Allows you to export a failed login attempts report for a custom period.
|
|||
|
|
5. View sign-in failure events based on error code.
|
|||
|
|
6. Helps export failed risky sign-ins alone.
|
|||
|
|
7. Exports a report on guest users’ sign-in failures.
|
|||
|
|
8. Segments failed sign-in attempts based on MFA enforced & not enforced.
|
|||
|
|
9. You can export the report to choose either All users or Specific user(s).
|
|||
|
|
10. The script can be executed with an MFA-enabled account too.
|
|||
|
|
11. Exports report results as a CSV file.
|
|||
|
|
12. The script is scheduler friendly.
|
|||
|
|
13. It can be executed with certificate-based authentication (CBA) too.
|
|||
