Connect Steam

The easy way: dashboard → Connections → Connect Steam and sign in through Steam. That's it.

Manual linking instead: enter your 64-bit SteamID (looks like 76561198000000000) and a free Steam Web API key. The API key is required for achievement sync.

Achievements not showing?

Steam hides game data unless your profile allows it. On Steam: your profile → Edit Profile → Privacy Settings → set Game details to Public. This is the #1 reason a connected Steam account shows nothing.

Steam is also the only platform that reports what you're playing right now, so the Smart overlay gives it priority the moment you launch a game.
