“Your organization requires you to change your pin” in my personal laptop?

Hi there

Im encoutering an issue which I dont know how it started.

I recently received my work laptop. Until then, I used my personal laptop to exchange mails with my company.

I noticed that the gmail account i used to exchange contact was being monitored by the company, which I was fine with that.

I have other emails i use for myself.

Today, I received the work laptop and notified then.

But then, at night, I realized when I was about to login in my personal laptop that the message "Your organization requires you to change your pin" appeared !

In my own personal laptop, which I found bizarre and dont recall giving anyone consent to do this.

I just received my own work laptop, what on earth are they doing in my personal laptop??

How do I approach this ?
