If save scumming counts as cheating, then yes. But otherwise, I’ve only ever used cheats in single player games and I really only use cheats if either the game sucks or the cheats I used didn’t effect gameplay. Some of the times I remember using cheats are:

Using the “fixme” command in Morrowind because I got stuck somewhere.

Using various cheats in the GTA games, after I had already beaten the main story, just so I can cause some mayhem.

Using the “giveall” command in Doom because I installed a weapon mod that required it.

Using the free cam that built into some emulators.

I think I remember using a cheat code to access unused content in at least one game, but I can’t remember what game that was.

While I haven’t played it yet, there is a PS2 (I think) game that requires using a cheat code to enable widescreen (or was it 720i, or maybe there was more than one game that did this, I can’t actually remember now).
