## 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.
