Is there a way to hide a Steam game from your recently played list?

A friend of mine said he's seen me playing a game (Batman: Arkham Origins) on Steam while I was at work. Since he only has two friends in his list I tend to believe him (ruling out a mix-up)

But the game does not show up on my recently played list. Is there a way to play a game without appearing in that list or to delete an entry?

Just to be sure, I changed my Steam password.

Solution 1:

No its not possible to delete or remove those entrys since they are all stored server side i assume. If you search you find people on reddit having similar issues, which can be traced back to a buggy steam beta version and free weekends showing wrong information on the beta client.

Maybe those bugs and your friend seeing you in a game you didnt even play at the time are related

Solution 2:

If you disconnect from the internet while playing the game, it won't count towards your hours played.

If you think someone else might have been on your account, Steam logs where people access your account from via IP address. So if you log into your account from a new computer, it will require email verification before you can login.
