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.

I am getting error 401 or no manifest code returned for old manifest ids

Try logging in with a Steam account, this may happen when using anonymous account.

Steam allows developers to block downloading old manifests, in which case no manifest code is returned even when parameters appear correct.

Why am I getting slow download speeds and frequent connection timeouts?

When downloading old builds, cache server may not have the chunks readily available which makes downloading slower. Try increasing -max-downloads to saturate the network more.
