I remember I was able to browse things like my profile and others’ profiles from the community tab in Steam. Lately, however, it seems that the community tab just shows me a page where I have to explicitly log-in with my Steam account name and password – even though I’m browsing from within the logged-in Steam client.
Is this normal? Is there anything I can do to make it authenticate automatically, or do I have to use the username and password manually?
It happens now and then, especially when your Steam client has been running for a long time.
The built-in browser drops your session cookies, for some reason, making your current login invalid.
To solve this, either log-in or restart your client.
