Whenever I try to upload to steam, I keep getting “Are you logging into the Steam client from a new computer? Here’s the Steam Guard code you’ll need to complete the process” bla bla… problem is I have nowhere to put this code in and as far as I know I cannot disable this feature.
I logged in on steam on the same pc and even a browser but it still asks. What can I do please?
I am uncertain if it will work but you could navigate to /ARKDevKit/ModTools/SteamCMD/ and run the steamcmd.exe file.
Then type in
.
You should get a response asking for a Guard key. Maybe it will work then.
- To be on the safe side, exit your normal SteamClient before.
In the DOS-style SteamCMD command prompt window that pops up when you first attempt to Upload to Steam, it should give you the option of inputting the SteamGuard value right there 
Worked like a charm. Thanks peeps :).
