A tool for checking if MFA is enabled on multiple Microsoft Services
MFASweep
MFASweep is a PowerShell script that attempts to log in to various Microsoft services using a provided set of credentials and will attempt to identify if MFA is enabled. Depending on how conditional access policies and other multi-factor authentication settings are configured some protocols may end up being left single factor. It also has an additional check for ADFS configurations and can attempt to log in to the on-prem ADFS server if detected.
Currently MFASweep has the ability to login to the following services:
- Microsoft Graph API
- Azure Service Management API
- Microsoft 365 Exchange Web Services
- Microsoft 365 Web Portal w/ 6 device types (Windows, Linux, MacOS, Android Phone, iPhone, Windows Phone)
- Microsoft 365 Active Sync
- ADFS
WARNING: This script attempts to login to the provided account TEN (10) different times (11 if you include ADFS). If you entered an incorrect password this may lock the account out.
