Stopping login attempts from mobile devices

Occasional Visitor

Hey Team.


We have a user who is having their account locked out, but only during business hours.


I suspect his account is set up on a device that has the old credentials but I have asked him to check his phones, tablets and home PC to no avail.


Is there a way to see what devices are attempting to login?  Or to stop authentication attempts from specific devices?

Yes, you can certainly check the Azure AD sign-in logs:

As well as selectively block/disable any of the devices he has, then re-enable them one by one until you find the culprit.
