Unable to login to Steam3
Ok so First I want to say that I read all the guide and I still have no succes Version: 2.4.6

I try with a less complex password, with and without steam guard, I always have the same result.
Please Help, thanks

I went to another steam account, purchase the game I wanted to downgrade, did the exact same thing as above, note that both account had the same exact password at this point of my test, and with this other steam account that procedure worked.
I still would like to have it work on my main account because there is other game I need to downgrade and I am not going to buy them all......
This error message is very specific in that you have provided the wrong username or password. If you are certain about your password, you have supplied the wrong username.
hello, I have the same issue even when disabling the firewall, my IDs are correct
I get this entry

You've been rate-limited for one reason or another. If you're spamming Steam or running a large number of instances, then don't.
yes sorry it happened after I got InvalidPassword many times, the original error was the following one

I found the issue, I changed my password and got rid of special characters in it, now it works
