Why can't I log into Overwolf's Steam Chat?
Steam has a "Steam Guard" mobile authentication system which will cause your Overwolf Steam IM chat to fail to log in.
This is due to the way our IM servers is communicating with the Steam mobile authentication API.
The Steam chat login error will say that either your username or password are incorrect, but note that if you have the mobile authentication system then this is your first stop to check.
Is there a workaround?
The only way to overcome this is to disable the mobile authentication from the Steam mobile app.
If this changes in the future, we will update this article 🙂
