Any way to tell which computers have been using my Steam account?

I recently installed Steam on my new gaming laptop and re-installed The Witcher 3. First thing I noticed is that it says the last time I played in was yesterday and I've played it for 68 hours. The thing is, I definitely didn't play it yesterday because my gaming PC has been packed up in storage for months. Also, I don't remember getting to 68 hours- last I remember, I was at 63 hours.

Is there some way to say what devices (if any) have logged onto Steam in the last few days? I'm going to change my password and stuff but I don't know if that's good enough. Thanks for any help.

Change your password, deauthorize all devices.

AFAIK, Steam does not offer that capability, but third party apps should do that.

Okay I changed my password. I'll try to deauthorize all devices. Not sure how though.

Thanks everyone. I think I got it squared away now.
