Forgot your Steam account - you can do that

If you have forgotten the access data for your Steam account, you do not have to despair. We'll show you what you can do instead.

How to get new Steam credentials

1. Open the stream application on your computer.
2. When logging in, you must click on "Forgot login information" and "Retrieve the old account".
3. Since you do not know your account name, follow the second option (see picture).
4. Now you can have your access data sent to you by email using the email address you used for registration or a serial key.
5. If you do not know the email address or the product key, you should look in old Steam file folders: In the "steamapps" subfolder there is a file folder that bears your user name.
