Frequently Asked Questions

Why am I prompted to enter a 2-factor code every time I run the app?

Your 2-factor code authenticates a Steam session. You need to "remember" your session with -remember-password which persists the login key for your Steam session.

Can I run DepotDownloader while an account is already connected to Steam?

Any connection to Steam will be closed if they share a LoginID. You can specify a different LoginID with -loginid.

Why doesn't my password containing special characters work? Do I have to specify the password on the command line?

If you pass the -password parameter with a password that contains special characters, you will need to escape the command appropriately for the shell you are using. You do not have to include the -password parameter on the command line as long as you include a -username. You will be prompted to enter your password interactively.
