A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Hi Mathew,
Thanks for the question.
Consider checking "Recent activity" at https://mysignins.microsoft.com > reviewing sign-in logs > resetting the password and signing out of unused devices.
The activity page could be blank because of sync issues. Consider signing out and back in, clear browser cache.
If it still shows blank, you may have to request for a backend check by Microsoft support, or your IT admin (in case of work account).
Hope this helps! Let me know if you have any further queries in the comments
